**** Updated March 2026 with confirmed demo details from Epson's Embedded World product briefing **** Introduction – Why Epson Matters for Embedded Systems in 2026 The transition to intelligent edge computing demands more than raw processing power. Modern embedded systems must sense, interpret, synchronise, and communicate with unprecedented precision whilst operating on minimal power budgets. Traditional component selections—mismatched sensor noise floors, inflexible wireless stacks, inflexible display interfaces—force engineers into costly compromises between accuracy, power efficiency, and system complexity. Epson addresses this challenge through integrated embedded solutions rather than point products. For over three decades, the company has invested in proprietary microfabrication technologies (particularly QMEMS—quartz microelectromechanical systems) that deliver measurement precision normally reserved for laboratory instruments, but packaged for industrial edge deployment. At Embedded World 2026, Epson will showcase five critical technology pillars that solve real engineering problems: ultra-low noise motion sensing, wireless IoT connectivity, display control architecture, precision timing, and voice guidance—each production-proven across demanding applications from structural health monitoring to autonomous robotics. This teaser introduces what you'll encounter on the stand and why Epson's approach matters for your next-generation embedded design. The Core Challenge – Precision at the Edge Edge devices face competing pressures: Measurement precision: Sensors must resolve subtle motion, vibration, or environmental signals without amplifying noise. A seismic accelerometer detecting microtremor, or an industrial vibration sensor predicting bearing failure, cannot afford noise floors that mask the signal they're trying to measure. Power efficiency: Battery operation demands sub-100 milliwatt operation for weeks or months between charging. Yet many precision sensors consume watts. System integration: Engineers waste design cycles interfacing incompatible components—scaling accelerometer signals, converting display protocols, synchronising timing across distributed sensors. Long-term stability: Deployed systems operate for years. Sensor drift, frequency aging, and thermal instability can render data unusable without expensive recalibration. Epson's approach addresses all four through coordinated technology choices rather than component-by-component optimisation. Epson's Foundation – QMEMS Technology and Embedded Systems Integration Epson's competitive advantage rests on QMEMS (quartz microelectromechanical systems) microfabrication, a proprietary technology delivering motion sensing with noise floors and stability characteristics previously achievable only in laboratory settings. Why Quartz, Not Silicon? Quartz resonators exhibit superior temperature stability and lower long-term drift compared to silicon MEMS. Whilst silicon dominates cost-sensitive applications, quartz-based motion sensing delivers: Ultra-low noise density: Down to 0.02 µG/√Hz for accelerometers (M-A370), 0.03°/√h for gyroscopes (M-G370) Exceptional bias stability: ±0.5 mG repeatability over years, enabling permanent infrastructure monitoring without recalibration Temperature-stable operation: Devices maintain performance across -40°C to +85°C industrial ranges Proven MTTF: 87,600+ hour operational lifetimes supporting decade-scale deployments Beyond Motion Sensing Epson's expertise extends beyond accelerometers and gyroscopes. The same precision-fabrication mindset informs: Display controllers maintaining image fidelity across resolution conversions Timing devices synchronising distributed sensor networks with nanosecond precision Voice guidance ICs enabling natural human-machine interaction Wireless modules integrating radio front-ends with embedded processors for seamless IoT integration Discuss Epson's Newest Products at Embedded World 1. Ultra-Low Noise Motion Sensing (M-A370 Accelerometer & M-G370 IMU) New at 2026: Epson highlights the recently mass-produced M-A370 ultra-low noise accelerometer and complementary M-G370 IMU (Inertial Measurement Unit), representing a generational leap in embedded motion sensing. M-A370 Accelerometer – Seismic-Grade Precision in Compact Form The M-A370 delivers what were previously laboratory specifications in a 48×24×16 mm rugged module: Key Specifications: Noise density: 0.02 µG/√Hz (1–10 Hz bandwidth)—enabling detection of subtle vibrations invisible to conventional sensors Bias stability: ±0.5 mG temperature error, ±0.1 mG annual repeatability—supporting years of continuous monitoring without recalibration Dynamic range: ±10 G with amplitude response flat to ±0.4 dB Output: Digital SPI/UART, eliminating analogue noise injection GNSS synchronisation: 1PPS input enabling multi-sensor temporal alignment across networked systems Operating life: 87,600 hours (10 years) at rated conditions Why This Matters: Engineers deploying structural health monitoring (bridges, buildings, tunnels), seismic observation networks, or machinery vibration analysis can now achieve measurement precision without laboratory-grade equipment or recurring calibration expense. The compact form factor integrates into smart meter networks, autonomous vehicle chassis monitoring, or industrial IoT gateways where space is constrained. Read our deep-dive into the new Epson M-A370 Accelerometer here . M-G370 IMU – Navigation-Grade Gyroscope & Accelerometer in One The complementary M-G370 IMU combines precision gyroscope with matched accelerometer for full six-degree-of-freedom inertial measurement: Key Specifications: Gyro bias instability: 0.8°/h (compared to 3–5°/h for conventional industrial gyros) Angular random walk: 0.06°/√h—enabling precise attitude determination with minimal drift Accelerometer range: ±8 G or ±16 G (software-switchable) Output rate: Up to 2000 Hz—sufficient for real-time control of stabilisation systems Power consumption: ~53 mW typical—enabling battery-powered wearables, drones, and mobile robotics Interface: SPI/UART digital output Why This Matters: Autonomous systems (drones, UGVs, mobile robots) require gyroscope precision that doesn't accumulate unbounded drift. The M-G370's low bias instability enables dead-reckoning (inertial navigation without external position updates) over timescales measured in minutes rather than seconds. For wearable devices, the low power consumption permits full-day operation on coin-cell batteries whilst maintaining gesture recognition, fall detection, or orientation tracking. You can read our breakdown of the full Motion Sensor Module range here . 2. Wireless IoT Connectivity – Seamless Edge Communication Epson's wireless portfolio addresses the fragmentation plaguing IoT deployments: incompatible protocols, inflexible frequency allocations, and integration challenges between radio and embedded processor. Product Focus at Embedded World: Epson offers integrated wireless modules combining RF front-end, baseband processor, and application processor in single packages, eliminating the custom integration burden of discrete components. Key Wireless Solution Categories: Sub-GHz and 2.4 GHz Solutions Low-power mesh networking (Zigbee, Thread, proprietary) Long-range, low-data-rate options for battery-powered sensors Channel hopping and frequency agility for industrial environments with RF interference Integration with Motion Sensing Combined accelerometer/gyroscope + wireless transceiver enabling condition monitoring nodes that detect vibration anomalies locally, then transmit alerts—reducing network traffic and cloud processing burden Example: Wireless vibration sensor continuously monitors bearing temperature and vibration signature; transmits only when predictive maintenance thresholds are exceeded GNSS Integration Precision timing alignment across geographically distributed sensor networks Critical for infrastructure monitoring where local vibration events must be time-correlated with regional seismic activity 3. Display Controllers – Bridging Legacy Systems and Modern Interfaces Industrial and automotive systems often face display architecture challenges: upgrading to higher-resolution outputs without redesigning entire camera or video subsystems, converting between incompatible interface standards (LVDS to HDMI, proprietary timing formats to MIPI). Epson Display Solutions: ToraFugu Scaler IC (S2D13V52) Flexible resolution scaling (e.g., converting 720p camera input to 1080p display output without quality loss) Colour space conversion and gamma correction Real-time performance—zero-latency upscaling for live camera feeds Automotive-grade reliability with extended temperature operation GoldenGate Bridge IC (S2D13V70) Interface protocol conversion (LVDS ↔ HDMI, parallel RGB ↔ MIPI) Timing format adaptation enabling legacy display panels to work with modern SoCs Low latency, deterministic operation for time-sensitive applications (vehicle safety systems, industrial monitoring) Why This Matters for Engineers: Display integration often consumes disproportionate design cycles. An existing industrial camera subsystem with LVDS timing cannot directly connect to a modern automotive SoC with MIPI CSI support. Rather than redesigning the entire camera pipeline, a single GoldenGate bridge IC performs real-time protocol translation, preserving capital investment in existing hardware and accelerating time-to-market. Read more about Epson's Display Controllers here . 4. Precision Timing Devices – Synchronising Distributed Systems Edge computing increasingly means distributed intelligence—multiple processors, sensors, and wireless nodes collaborating across a facility, vehicle, or smart infrastructure network. Synchronisation accuracy determines system reliability. Epson Timing Solutions: Crystal Oscillators and Real-Time Clocks Ultra-stable frequency sources (parts per billion aging rates) Temperature-compensated oscillators (TCXO) for outdoor and industrial environments GNSS-disciplined timing enabling nanosecond synchronisation across continents Application Examples: Smart Grids: Multiple substations must synchronise power measurements to microsecond precision for fault detection and load balancing Autonomous Vehicles: LiDAR, camera, and radar fusion requires timing alignment to sub-microsecond accuracy—clock instability directly impacts object detection reliability Structural Health Monitoring: Accelerometers deployed on different floors of a building must timestamp events with microsecond precision to calculate vibration propagation velocity 5. Voice Guidance and Audio ICs – Natural Human-Machine Interaction As embedded systems become more autonomous, natural voice interaction replaces keypad-based control. Epson's voice guidance ICs combine speech synthesis, noise cancellation, and audio amplification in low-power modules. Voice Guidance ICs at Embedded World: Text-to-Speech Synthesis Pre-recorded phoneme libraries enabling arbitrary phrase generation Multiple languages and accents Real-time processing at <100 mW power consumption Ambient Noise Cancellation Dual-microphone input with adaptive filtering Enables voice command recognition in factory floors, moving vehicles, and outdoor environments Critical for wearable devices and hands-free operation Audio Amplification Class-D amplifier sections for speaker drive Efficient power delivery—minimal thermal dissipation even at extended operation Integration with Motion Sensing Voice guidance triggered by motion events (e.g., "Warning: vibration anomaly detected on bearing 3") Gesture recognition enabling mute/unmute via wearable motion sensors Discover more about Epson audio solutions here . What to Expect on the Ineltek Stand at Embedded World The Ineltek-Epson stand (Hall 3A, Stand 3A-417) will feature three live demonstrations showcasing production-relevant engineering solutions. Each is built around a real design challenge - not a bench exercise. Demo 1: Automotive Local Dimming Controller A standalone hardware IC analyses video input to control up to 2,048 LED backlight zones, improving LCD contrast and reducing power consumption in automotive displays including HUDs. The demo runs on an FPGA (IC samples are at TS stage), with an evaluation board and configuration tool available to take away. Key capabilities on show: Light Spread Function (LSF) compensation storing up to 15 LSFs to correct for panel-specific light diffusion; defect compensation that automatically boosts surrounding LEDs if one fails; driver-agnostic protocol support; and resolution support to approximately 2.5K without de-warping, or 1920x1080 with it. For engineers wrestling with the contrast limitations of conventional PWM dimming or the integration complexity of discrete zone-control architectures, this is worth 20 minutes. SEMSATEC (integration) and Nietzsche (backlight) will also have representatives available for customers without in-house display integration capability. Demo 2: Battery-less Energy Harvesting System This is arguably the most forward-looking demonstration on the stand. Epson's 16-bit S1C17F63 MCU is powered entirely by a Lightricity indoor solar module and an E-Peace PMIC - no battery, no coin cell. The system drives an e-paper display, with a red LED indicating when the display content is not current. The relevance is regulatory as much as technical: incoming EU rules will restrict coin cells in consumer products, and this demo shows a production-credible path to fully battery-less IoT and ESL designs. The S1C17F63's sleep-mode power consumption is low enough to make this viable where competing MCUs - including Nordic devices - are not. Lightricity and E-Peace will have representatives present. Demo 3: High-Precision IMU An Epson IMU is mounted on a toy drone, with its real-time movement mirrored in a 3D animation on an adjacent display. The animation remains stable as the drone moves - demonstrating the IMU's superior bias calculation relative to lower-cost alternatives where drift accumulates visibly within seconds. No explanation needed: the drift difference between Epson and a generic MEMS gyroscope is immediately apparent on screen. Beyond the Trade Show – From Evaluation to Deployment Epson offers structured support pathways for engineers evaluating solutions: Evaluation Kits (1–2 weeks) Complete development boards for M-A370, M-G370, and wireless modules Pre-configured firmware enabling immediate functional assessment Technical support for design-in questions Feasibility Studies (2–4 weeks) Custom application evaluation using your specific environmental conditions Noise floor measurement, power consumption analysis, and thermal characterisation Whitepaper documenting results and design recommendations Design Partnerships (3–12 months) Full system integration support from concept through production Application-specific firmware optimisation Qualification assistance (automotive AEC-Q, industrial IEC 61508, medical FDA) Call to Action – Meet Epson at Embedded World 2026 Option 1: Book a Pre-Scheduled Technical Consultation Reserve 30 minutes with Epson applications engineers to discuss your specific requirements.

Request tickets: https://www.ineltek.co.uk/contact FAQs - Epson Product Showcase Q. How do Epson's QMEMS accelerometers compare to conventional silicon MEMS on price and performance? A: Epson QMEMS delivers 5–10× lower noise density and superior long-term stability, justifying higher unit cost for applications where measurement precision is non-negotiable (seismic monitoring, structural health, precision machinery). For cost-sensitive applications accepting ±1°/h gyro drift or 0.5 µG/√Hz noise floors, conventional silicon MEMS remain appropriate. Epson's value proposition targets applications where recalibration cost, system reliability, or regulatory requirements make precision economics favourable. Q: Can the M-A370 accelerometer and M-G370 IMU be used together for complete 6-axis inertial measurement? A: Yes. Epson accelerometer and gyroscope modules are matched in bandwidth, noise characteristics, and temperature stability, enabling seamless sensor fusion. Many engineers combine M-A370 accelerometer with M-G370 gyroscope for custom 6-axis inertial systems optimised to specific application requirements (e.g., emphasis on ultra-low noise for vibration analysis plus gyro for orientation tracking). Q: What is the typical timeline from evaluation kit to production deployment? A: 3–6 months for straightforward motion sensing applications; 6–12 months for complex system integration (display scaling plus wireless plus timing synchronisation). Epson feasibility studies (2–4 weeks) accelerate timeline by identifying integration challenges early. Customer-specific firmware optimisation typically adds 4–8 weeks. Q: Do Epson wireless modules support standard protocols (Zigbee, Thread, Bluetooth) or are they proprietary? A: Epson offers both standards-based (Zigbee 3.0, Thread, IEEE 802.15.4) and proprietary low-power mesh implementations. Standards-based options simplify interoperability with third-party devices; proprietary stacks optimise range, power consumption, or latency for specific applications. Technical team can advise on protocol selection based on your ecosystem requirements. Q: How does the GoldenGate Bridge IC maintain video synchronisation during LVDS-to-HDMI conversion? A: The bridge IC performs deterministic protocol translation with <1 microsecond latency variation, maintaining frame synchronisation and colour fidelity across the conversion. Real-time performance enables live camera feeds without visible artifacts or temporal desynchronisation—critical for automotive safety systems and industrial vision applications. Q: Are Epson motion sensors suitable for harsh industrial environments (vibration, temperature extremes, moisture)? A: Yes. Epson accelerometers and IMUs operate across -40°C to +85°C (some models to +100°C). Sealed aluminium and stainless steel packaging provides IP67 protection (dust and water resistant). MTTF specifications (87,600+ hours) support long-term outdoor and industrial deployment. Customer experience includes seismic monitoring stations (exposed to weather), railway infrastructure (vibration and temperature cycling), and oil/gas field monitoring. Q: What is Epson's approach to long-term product availability and supply chain resilience? A: Epson maintains 10–15 year product lifecycle for sensor modules, supporting infrastructure and industrial customers with long-term requirements. TSMC and Samsung foundry partnerships ensure manufacturing flexibility. Regional distribution through partners like Ineltek reduces supply chain vulnerability. Critical components include buffer stock management and flexible allocation during demand spikes.

Introduction: Why Pressure Sensing Matters in Modern Domestic Appliances For most of its history, a domestic appliance did one job. A gas meter counted gas. A blood pressure monitor inflated a cuff. A coffee machine pushed water through grounds. Today, those same devices are expected to connect to the cloud, respond to safety events in real time, operate for years on a single battery, and report data accurately enough for billing purposes. Pressure sensing is central to all of it. Whether it is detecting a gas leak before it becomes dangerous, compensating for altitude differences in a weather station, or ensuring a vacuum sealer reaches the correct negative pressure, the quality and characteristics of the pressure sensor define the performance of the whole system. Engineers specifying these components face a familiar set of trade-offs: measurement range, accuracy, power consumption, package size, and interface compatibility. HopeRF, a Chinese manufacturer with its own ASIC design, MEMS sensor chip design, and in-house packaging and calibration capability, has developed a range of pressure sensors specifically suited to these demands. This article examines four devices available through Ineltek: the 6862i barometric pressure sensor, the HPS700A-ZM absolute pressure sensor, the HPSxxxGS gauge pressure sensor series, and the PTM002 ceramic resistive pressure transmitter. What HopeRF's Pressure Sensor Range Addresses The challenge for designers of domestic appliances is that "pressure sensing" covers an enormous variety of physical requirements. A smart gas meter needs a barometric sensor that can detect the subtlest pipeline fluctuations while consuming almost no power over a ten-year battery life. A blood pressure monitor needs a gauge sensor with a tight accuracy specification and a reliable MEMS structure. A coffee machine or vacuum cleaner needs something that can survive repeated pressure cycles and routine liquid exposure. A portable air pump or weather station needs a compact, waterproof absolute pressure device. HopeRF's range maps onto these requirements with four distinct product families, each built around a 24-bit ADC, an I2C digital interface, and factory calibration so the host microcontroller receives compensated, ready-to-use data without needing to implement its own correction algorithms. Features of HopeRF Pressure Sensors Addressing the Core Design Challenges The 6862i: Barometric Sensing for Smart Gas Meters and IoT The 6862i is HopeRF's digital absolute barometric pressure sensor, developed specifically with smart gas metering in mind. It uses a capacitive sensing principle which maintains high precision across temperature changes and delivers 24-bit pressure and temperature results through an I2C interface. Its standout characteristic for battery-powered applications is power consumption. Standby current is 0.5µA (typical), which is fundamental in a gas meter expected to operate for years without a battery change. The 6862i supports three operating modes (standby, command, and background) and includes an internal FIFO buffer capable of storing up to 32 sets of measurement data. This allows the host processor to be woken infrequently to read a batch of readings rather than polling continuously leading to a significant system-level power saving. The sensor covers a pressure range of 300mBar to 1200mBar, with absolute accuracy of ±1.0mBar and relative accuracy of ±0.1mBar. Temperature measurement is also integrated, with ±0.5°C typical accuracy and a range of -40°C to +85°C. The device is individually calibrated at the factory, with calibration coefficients stored in on-chip registers and used automatically for compensation. The waterproof design and compact 6.8 x 6.2 x 3.1mm footprint make it practical for portable and outdoor installations. In a smart gas metering system, the 6862i does more than simply detect current pressure. When pressure drops abnormally, the system can trigger automatic valve closure, transmit alerts through an IoT module, and log data for analysis creating what HopeRF describes as a complete safety loop of detection, cutoff, alarm, and reporting. The sensor also enables pressure and temperature compensated volume calculation, which is essential for converting operating volume to standard volume for accurate billing. The HPS700A-ZM: High-Range Absolute Pressure for Portable and Industrial Use The HPS700A-ZM is a MEMS absolute pressure sensor with an I2C interface targeting a much higher pressure range: 0kPa to 1600kPa. This makes it suitable for portable air pumps, adventure and sports watches, weather stations, and industrial pressure and temperature monitors. Like the 6862i, it uses a 24-bit ADC and delivers internally compensated data, removing the need for external correction on the host MCU. Standby current is below 0.1µA (even lower than the 6862i) and supply voltage spans 1.8V to 3.6V, making it compatible with a wide range of low-power embedded systems. The package is compact at 3.8 x 3.6 x 1.15mm. Pressure absolute accuracy is ±2.0kPa over the 0 to 700kPa range from -20°C to +60°C, with relative accuracy of ±1.5kPa over the same conditions. Temperature accuracy is ±0.5°C at +25°C. The device supports I2C clock frequencies up to 400kHz and provides both compensated and uncompensated data readback options - useful in designs where the application processor may wish to apply its own post-processing. Every device is factory-calibrated for sensitivity and offset, with trim values stored in 128 bytes of on-chip NVM. The HPS700A-ZM uses an oversampling rate (OSR) system adjustable from 128 to 4096, allowing the designer to trade conversion time and current consumption against measurement precision. At OSR 128, conversion time is 2.1ms and average pressure measurement current is 2.9µA; at OSR 4096 it rises to 65.6ms and 91.8µA. This flexibility makes it straightforward to optimise for either accuracy or power depending on the application duty cycle. The HPSxxxGS Series: Gauge Pressure for Medical and Household Appliances The HPSxxxGS series takes a different approach. Rather than absolute barometric sensing, these are gauge pressure sensors measuring pressure relative to ambient, available in four measurement ranges: ±10kPa, ±40kPa, ±100kPa, and ±200kPa. The corresponding part numbers are HPS010GS, HPS040GS, HPS100GS, and HPS200GS, each available in tube or reel-and-tape packaging. The application list for this series reflects a broad set of domestic and medical equipment: electronic blood pressure monitors, oxygen concentrators, air wave therapy devices, massage chairs, air mattresses, sleep aid neck pillows, smart vacuum cleaners, vacuum juicers, beer machines, coffee machines, and vacuum pumps. The SOP6 SMD package makes board assembly straightforward, and the RoHS-compliant construction is a standard requirement for consumer product markets. Electrically, the HPSxxxGS operates from 3.3V or 5.0V supplies, with an operating current of 1.60mA and a standby current of just 200nA. The 24-bit ADC supports oversampling rates from 256x up to 32768x, with corresponding conversion times from 1.54ms to 42.18ms. Total accuracy is ±1.5% of full scale across the -20°C to +85°C range. The I2C interface runs at up to 400kHz. The series integrates both a MEMS pressure chip and a signal conditioning chip in a single package. Digital compensation of zero point, sensitivity, temperature drift, and nonlinearity is applied internally, so the calibrated output is directly usable by the host MCU. The output is a linear 24-bit signed value, converted to a pressure reading using a simple linear transfer function with coefficients A and B provided per part number in the datasheet. The PTM002-2500K-G: Ceramic Resistive Pressure for Liquid and High-Pressure Applications The PTM002-2500K-G is the most specialised product in the range. It is a ceramic resistive pressure transmitter with a stainless steel (SUS304) housing, designed specifically for direct contact with liquid media in applications such as drinking water systems, food processing equipment, and domestic life appliances. Working pressure spans 0MPa to 2.5MPa, accuracy is ±1.0% full scale (covering linearity, hysteresis, repeatability, and calibration), and the full error band is ±2.0% full scale from 0°C to +100°C. Protective pressure is 3x full scale and burst pressure is 5x. The device is rated for over 2 million full-scale pressure cycles; a demanding specification that reflects its use in equipment that pressurises repeatedly in everyday use. IP65 protection and a G1/8 female thread pressure connection complete the mechanical specification. Unlike the other three sensors in this overview, the PTM002 connects via a four-wire lead (red: Vcc, black: Vss, green: SCL, yellow: SDA) rather than a surface-mount footprint. The I2C interface operates with a clock frequency of up to 1MHz. Operating temperature is 0°C to +100°C and supply voltage is 1.8V to 3.6V.

The 6862i is tailored specifically for this application. A smart gas meter integrating the 6862i can monitor pipeline pressure continuously, detect anomalies such as leaks or ruptured connections, trigger automatic valve closure, and relay alerts through a wireless module all while running from a battery expected to last several years. The sensor's FIFO buffer means the meter's MCU can spend most of its time in deep sleep, waking periodically to collect a batch of stored pressure readings rather than remaining active during measurement. Beyond safety, the 6862i's combined pressure and temperature sensing enables accurate standard volume calculation. Gas volume varies with both temperature and barometric pressure, and regulations in many markets require that billing reflect standardised conditions rather than raw operating volume. The 6862i provides both the pressure and temperature data needed for this correction in a single package. HopeRF also offers complementary Sub-G FSK and LoRa wireless communication solutions supporting WM-Bus and LoRaWAN networking which is a useful consideration when specifying the full meter system rather than the sensor in isolation. Medical and Wellness Devices The HPSxxxGS series is well suited to the medical and wellness segment. Blood pressure monitors, oxygen concentrators, and air wave therapy devices all require gauge pressure sensing in the range covered by the HPS010GS to HPS100GS. These are devices where accuracy, repeatability, and reliable MEMS construction matter alongside a compact SMD package that fits the constrained PCBs typical of consumer medical equipment. Massage chairs, air mattresses, and sleep aid neck pillows similarly use gauge pressure sensing to regulate air chamber inflation. The 200nA standby current of the HPSxxxGS series is useful here too, in designs that spend extended periods in a monitoring or standby state between adjustment cycles. Small Kitchen and Household Appliances Coffee machines and other pressurised appliances present a different set of requirements: moderate pressure ranges, tolerance for repeated cycling, and interface simplicity. The HPS040GS (±40kPa) or HPS100GS (±100kPa) are natural candidates for vacuum and low-pressure applications in this category, while the ceramic resistive PTM002 is relevant where the sensing element may come into contact with liquids e.g. in drinking water systems, food processing, and similar environments where stainless steel construction and IP65 protection are necessary. Smart vacuum cleaners also appear on the HPSxxxGS application list. Sensing the differential pressure across the filter allows the device to detect blockages and alert the user, and the SOP6 package fits easily onto the compact control PCBs typical of modern cordless vacuum designs. Weather Stations and Portable Instruments Compact weather stations, altimeters, and portable data loggers represent a significant application for barometric sensors. The 6862i's waterproof design and operating range down to 300mBar give it useful altitude headroom, while the HPS700A-ZM's extremely low standby current (<0.1µA) makes it an attractive choice for adventure watches and GPS devices where battery life is critical. Both devices deliver the temperature measurement needed for altitude calculation and meteorological data logging in a single component. Conclusion and Call to Action HopeRF's pressure sensor range gives embedded engineers a coherent toolkit for addressing the sensing requirements of modern domestic appliances. The 6862i covers barometric and gas metering applications with industry-leading standby power. The HPS700A-ZM handles high-range absolute pressure in portable and industrial instruments. The HPSxxxGS series covers gauge pressure across four ranges for medical, wellness, and household appliance markets. And the PTM002 brings ceramic resistive sensing and stainless steel construction to applications where liquid contact, high-pressure cycles, and IP-rated mechanical construction are required. All four devices share the same fundamental architecture: a MEMS sensing element, a 24-bit ADC, factory calibration, and an I2C digital interface reducing integration risk and simplifying firmware development regardless of which variant a project demands.

The internal signal conditioning provides temperature-compensated, linearised digital output directly via I2C, removing the need for user calibration or complex compensation firmware.

The Accidental Hacking of 7,000 Robot Vacuums proves that manufacturers are still shipping IoT-enabled products with serious security vulnerabilities Sammy Azdoufal just wanted to steer his new DJI Romo robot vacuum with a video game controller. While building his own remote-control app with the help of an AI coding assistant, he reverse-engineered how the vacuum communicated with DJI's cloud servers in order to extract an authentication token. That token, it turned out, worked for rather more than just his own device. The same credentials that allowed him to see and control his own device also provided access to live camera feeds, microphone audio, maps, and status data from nearly 7,000 other DJI Romo vacuums across 24 countries. With that access, he could view real-time video from inside people's homes, activate microphones, and compile 2D floor plans of the buildings the vacuums were cleaning. He could also identify approximate locations from the devices' IP addresses. Admirably, Azdoufal did not exploit the access. He reported his findings to The Verge, which contacted DJI, and the vulnerability was patched. But the incident made headlines precisely because it illustrated something that cybersecurity professionals have been warning about for years: the IoT industry has a deeply ingrained habit of treating security as an afterthought, rather than a critical feature that should be built into the silicon from the outset. The DJI case is instructive not just because of what went wrong, but because the specific failures it exposes are the tip of a very big iceberg. By recent estimates there are approximately 22 billion IoT devices globally (at time of writing Feb 2026) - so even a small fraction of these having basic vulnerabilities leaves many millions of households at risk of serious privacy breaches. Fortunately, the solutions to all of these flaws exist today, in hardware, at a cost and complexity level that any product team can justify. What Actually Went Wrong – The Four Vulnerabilities SEALSQ, the specialist digital identity and secure element manufacturer whose VaultIC devices are distributed by Ineltek in the UK, analysed the reported failures and identified four distinct security breakdowns that contributed to the breach. Credentials The first and most significant was the use of identical credentials across all devices. Rather than issuing each DJI Romo with a unique cryptographic identity, the authentication architecture apparently relied on shared credentials that, once compromised for one device, provided access to the entire fleet. This is not a DJI-specific problem. It is arguably the most common single security error in connected consumer electronics, driven by the operational simplicity of not running a per-device key provisioning process during manufacturing. Pin Bypass The second failure was a PIN bypass on the camera system, which meant that even a secondary layer of access control could be circumvented without knowledge of the device owner's credentials. Poor firmware update protocol The third was the possibility of loading rogue firmware onto a device indicating that firmware update processes were not protected by cryptographic signature verification. This means that potentially harmful software of completely arbitrary origin can and was executed on the vulnerable hardware. Undisclosed A fourth category of vulnerabilities, not fully disclosed in public reporting at the time of writing, remains under investigation. Together, these failures describe a device that had no reliable way to prove its own identity to a server, no way to establish that a secure session was genuinely with its rightful owner, and no way to verify that the firmware it was running had been issued and authorised by the manufacturer. These are not obscure or difficult problems. They are precisely what hardware secure elements are designed to solve. What SEALSQ VaultIC Secure Elements Would Have Done Differently The VaultIC292 and VaultIC408 are tamper-resistant secure microcontrollers from SEALSQ, designed to provide connected devices with the cryptographic foundation that the DJI Romo demonstrably lacked. Understanding how they address each failure mode makes the case clearly. Unique device identity and per-device TLS sessions The fundamental requirement for IoT security is that every device has a unique, verifiable identity that cannot be cloned or shared. The VaultIC292 is specifically designed to provide exactly this: each chip contains a unique ECC P-256 key pair and X.509 certificate, provisioned during SEALSQ's certified production process under the VaultiTrust service. When the device communicates with a cloud server, it presents its certificate to establish a unique TLS 1.3 session that is cryptographically bound to that specific device alone. Gaining the credentials of one device provides access to nothing else on the network. The shared-credential vulnerability is structurally impossible when each device has its own certificate. Critically for manufacturers, this does not require establishing a secure production environment. SEALSQ can deliver VaultIC chips pre-provisioned with unique digital identities and birth certificates, tailored for connection to AWS, Azure, or a private cloud platform. DJI's existing production lines and EMS partners would not need to change their processes at all. Hardware-enforced firmware signature verification Rogue firmware attacks rely on the ability to push unsigned software to a device without detection. VaultIC secure elements address this through cryptographic code signing and verification: firmware updates are signed by the manufacturer's private key, and the secure element verifies that signature before any update is accepted. Without a valid signature from an authorised key – which exists only in the manufacturer's secure environment – the device rejects the update entirely. The key material that makes this possible lives inside the tamper-resistant hardware of the secure element, protected against side-channel attacks, physical probing, and voltage/temperature manipulation by dedicated hardware countermeasures. It cannot be extracted by software and cannot be copied from one device to another. Access control that cannot be bypassed in software The PIN bypass in the DJI case represents a failure of software-only access control: when authentication logic runs on a general-purpose processor, it can in principle be circumvented by someone with sufficient knowledge of the software stack. VaultIC secure elements move authentication logic into hardware that executes independently of the host processor, in a security domain that the host application cannot manipulate. Challenge-response authentication on the VaultIC408, for example, uses ECDSA digital signatures that require possession of the device's private key – a key that never leaves the secure element and cannot be extracted even if the host MCU is fully compromised. VaultIC292 and VaultIC408 – Which Fits Your Design? SEALSQ offers two VaultIC products suited to the IoT authentication use case, with the choice driven principally by required cryptographic capability and interface preference. Feature VaultIC292 VaultIC408 Primary Use Case Secure TLS identity, firmware verification, USB-C and QI auth Full-featured secure storage, advanced authentication, IP protection Cryptographic Algorithms ECC NIST P-256 (ECDSA, ECDH) AES 128/192/256, RSA up to 2048-bit, ECC up to 576-bit, GCM/GMAC Memory 1,680 bytes NVM (5 key pairs + 2 X.509 certificates) Up to 16kB EEPROM file system Communication Interface I2C (up to 100kHz) SPI and I2C Security Certification EAL5+ ready hardware EAL5+ ready hardware; FIPS 140-3 Level 3 CMVP (v1.2.x) Pre-Provisioning Service VaultiTrust – unique identity, AWS/Azure/private cloud ready VaultiTrust – unique identity, AWS/Azure/private cloud ready Package DFN-6 (2x3mm), UDFN-8 (2x3mm) SOIC-8 (5x8mm), QFN-20 (4x4mm) Supply Voltage 1.62V to 5.5V 1.62V to 5.5V Operating Temperature -40°C to +105°C -40°C to +105°C For a connected consumer or industrial IoT device primarily requiring unique device identity, TLS session establishment, and firmware signature verification – the exact failure modes exposed in the DJI case – the VaultIC292 is the appropriate solution. Its small package, simple I2C interface, and pre-provisioning capability make it straightforward to integrate into new designs or retrofit into existing products with minimal bill-of-materials impact. The VaultIC408 suits applications requiring broader cryptographic services: full AES encryption, RSA-based authentication, role-based access control, and secure file storage for more complex identity and entitlement management scenarios. Both products are built on the same silicon heritage as national ID cards, e-passports, bank cards, and SIM cards; the applications where security has been pressure-tested most rigorously for the longest time. Industry Applications – Where These Vulnerabilities Are Hiding The failures exposed in the DJI case are far from unique to premium consumer robotics. The same architecture – shared credentials, unsigned firmware, software-only access control – is replicated across categories including smart energy meters (where firmware integrity is a regulatory requirement under UK Smart Metering Implementation Programme standards), industrial IoT sensors (where device authentication is required under IEC 62443), IP cameras and surveillance systems, medical remote monitoring devices, and connected automotive accessories. Any product that connects to a cloud back-end, accepts over-the-air firmware updates, or handles data that an attacker would find valuable is a candidate for the same class of attack. The commercial argument for addressing this at the silicon level rather than through software patches is straightforward: a software authentication mechanism can be bypassed by someone who controls the host processor; a hardware secure element cannot be compromised even if the host is fully owned. And the cost of adding a VaultIC292 to a product BOM is a small fraction of the cost of a single product recall, a regulatory investigation, or the reputational damage of appearing in mainstream technology news as the device whose security failed catastrophically. Conclusion – One Accidental Hack Tells the Whole IoT Security Story The DJI robot vacuum story ended well because Sammy Azdoufal turned out to be curious rather than malicious. Not every discoverer of a vulnerability will make the same choice. As AI coding tools lower the barrier to reverse-engineering device protocols, and as the installed base of inadequately secured IoT hardware continues to grow, the number of people capable of finding and exploiting these vulnerabilities is increasing faster than the industry is fixing them. The good news is that the technical solution is not complex, it is not expensive, and it does not require manufacturers to redesign their products or rebuild their production processes. A secure element like the VaultIC292 or VaultIC408 integrates into existing designs over a standard I2C or SPI interface, arrives pre-provisioned with unique device identities through the VaultiTrust service, and closes the specific vulnerabilities that turn a fleet of robot vacuums into a surveillance network.

FAQs - IoT Secure Elements Q.  What specific vulnerabilities does a secure element like VaultIC292 address in a connected IoT product? A.  A secure element addresses three of the most common IoT vulnerability classes: the use of shared device credentials (by providing every device with a unique cryptographic identity and certificate), software-only access control bypasses (by executing authentication logic in tamper-resistant hardware independent of the host processor), and rogue firmware installation (by requiring all firmware updates to carry a valid cryptographic signature before execution). These three classes account for the majority of publicly disclosed IoT breach incidents, including the February 2026 DJI Romo case. Q.  Does adding a VaultIC secure element to a product require changes to the existing production line? A.  Not necessarily. SEALSQ's VaultiTrust service delivers VaultIC292 chips pre-provisioned with unique device identities and X.509 certificates configured for AWS, Azure, or a private cloud. The manufacturer's existing production line and EMS partners do not need a separate secure provisioning process. Q.  What is the difference between the VaultIC292 and VaultIC408? A.  The VaultIC292 is optimised for TLS and MATTER device identity, firmware signature verification, and simple I2C integration in a compact DFN-6 or UDFN-8 package. The VaultIC408 provides a broader cryptographic service set including AES-256, RSA-2048, role-based access control, and a 16kB secure file system, making it suitable for more complex authentication and secure storage requirements. Both are EAL5+ ready and VaultIC408 is certified FIPS 140-3 CMVP. Both support industrial temperature ranges. Q.  Why is hardware-based IoT security more effective than software-only approaches? A.  Software authentication mechanisms can be bypassed by an attacker who controls or has compromised the host processor. A hardware secure element executes its cryptographic operations in an isolated security domain that cannot be manipulated by the host application, even if the host is fully compromised. Private keys stored in a secure element cannot be extracted via software attacks, side-channel analysis, or physical probing, making the root of trust genuinely tamper-resistant rather than merely difficult to attack.
