The Future of Farming: The Electronics that will transform the Agritech landscape


Image of precision application of agricultural spray powered by GPS module technology

Farming has been a vital part of human civilisation since the dawn of time. Throughout history, farmers have relied on their knowledge, experience, and intuition to cultivate crops and raise livestock. However, in recent years, the agriculture industry has undergone a significant transformation, thanks to advances in technology. Agritech and for our part, the electronics that drives it, is leading the way in this revolution, with cutting-edge tools that are changing the way farmers work and improving the efficiency and sustainability of their operations. In this article, we'll explore the latest innovations in Agritech and how they are shaping the future of farming.


(NB There doesn’t seem to be a definitive proper noun for Agritech, Agtech, Agri-tech so we’re going to refer to this category as Agritech and hope that sticks!)


The Existential Necessity of Securing Future Food Supply for a Growing Global Population

The world's population is expected to reach 9.7 billion by 2050, and that means we will need to produce 70% more food than we do today just to keep up with demand. This increase in demand for food is putting an enormous strain on our agricultural systems, which are already struggling to keep pace. Agriculture is responsible for 70% of global freshwater consumption, and it accounts for 25% of all greenhouse gas emissions. If we continue to rely on outdated farming methods, we risk depleting our natural resources and exacerbating climate change.


The time for action is now

If three years of disruption, turbulence and insecurity across the global supply chain have taught us anything, it is that the food system is ripe for a change. With pressure from demographic shifts, climate struggles and geopolitical conflict, piling on top of pervasive issues such as food insecurity, diet-related health problems, and the weakening of ecosystems worldwide, this change can't happen soon enough. One example, above all, last year the UN estimated that up to 40 % of the planet’s land is degraded, directly affecting half of humanity and threatening roughly half of global GDP (US$44 trillion). This gives you some idea of the scale of these issues are and how critical is for us to all to take action.


The UK has a long history of agriculture, and it is a critical sector of the economy, contributing over £24 billion annually. However, like many other countries, the UK faces significant challenges in maintaining a sustainable and productive agricultural system. To address these challenges the UK government has launched a series of initiatives to promote the adoption of Agritech technology.


For our part, we’re eager to make a contribution by getting involved from the ground up; helping Agritech start-ups through to growing enterprises to deliver the best electronic component solutions to ensure these vital Agritech projects thrive.


The role of Agritech in the future of farming

By harnessing the power of technology, we can make farming more efficient, sustainable, and productive. For example, smart irrigation systems can help farmers reduce water usage by up to 50%, while precision agriculture allows farmers to apply the right amount of fertiliser and pesticides only where they are needed, reducing waste, and minimising the impact on the environment. Coupling such innovations with computer vision and vertical farming has significantly improved farmers’ crop yields, while reducing resource consumption.


Agritech electronics have the potential to improve food security by making farming more resilient to climate change. As extreme weather events become more common, farmers need tools that can help them adapt to changing conditions. For example, drones equipped with thermal cameras can detect crop stress before it becomes visible to the naked eye, allowing farmers to act before it's too late.


The Electronics and Technology Driving the Agritech Revolution

Agritech electronics encompass a wide range of technologies, from sensors and drones to robotics and machine learning. Perhaps the most important infrastructure that most electronic Agritech projects have in common is the internet of things (IoT). IoT devices are small, low-cost sensors that can be embedded in farming equipment, such as tractors, irrigation systems, and storage facilities. These sensors can collect data on things like soil moisture, temperature, and humidity, which can be used to optimise crop production and reduce waste. The always on, always on-line, remote management capabilities gives a level of 24/7 monitoring and autonomy that is just not possible with traditional farming.


Let’s take a bit more of a deep dive into some of the technologies already tried and tested in the field, as well as some of our class-leading semiconductor manufacturers making it happen.

Vertical Farming

One of the most promising areas of Agritech electronics in the UK is vertical farming. Vertical farming involves growing crops in stacked layers, using artificial lighting and climate control to create optimal growing conditions. This technique has several advantages over traditional farming, including higher crop yields, reduced water usage, and a smaller carbon footprint. Several companies in the UK are already using vertical farming to produce a range of crops, including salad greens, herbs, and strawberries. Indeed Ineltek has already provided MCU solutions from Nuvoton for management and control of the indoor lighting systems required for these installations. We have also implemented Espressif’s wi-fi modules to give remote management and OTA upgrades to vertical farming operations of size and scale.


Nuvoton’s AgriTech capable MCU the MA35D1

Nuvoton's MA35D1 is a microcontroller unit has a specification ideally suited for use in agricultural technology.

One of the key benefits of the MA35D1 is its low power consumption, making it safe for the environment. This means that it can be used in battery-powered devices for extended periods without needing to replace or recharge the batteries. This feature is particularly beneficial in Agritech applications, where devices may need to be left in the field for extended periods of time.


Another benefit of the MA35D1 is its high level of integration. It includes a range of peripherals, such as ADCs and PWM controllers, which can be used to control a range of devices such as motors and sensors. This integration reduces the need for external components, making it a cost-effective solution for Agritech applications.

Furthermore, the MA35D1 offers a range of connectivity options, including USB, Ethernet, and CAN bus. This allows for easy integration with other devices and systems, enabling real-time data collection and analysis. Read more about the MA35D1 in our deep dive into this mighty MCU here.


Precision Agriculture and Autonomous Machinery

Another area where Agritech electronics are making a difference in the UK is precision agriculture. Precision agriculture involves using data analytics, sensors, and other technologies to optimise crop production. By analysing data on soil moisture, temperature, and other factors, farmers can make more informed decisions about when to plant, fertilise, and harvest their crops. This can lead to higher yields, lower costs, and reduced environmental impact. Regular GPS / GNSS positioning systems can only deliver accuracy of c. 0.5m at present which is not accurate enough in practical applications where a harmful chemical or 16t machine in the wrong place could be disastrous. This is where the vastly superior accuracy of Ultra Wideband, UWB, comes in.


Qorvo’s DW1000 Next-Gen Positioning Sensors

Qorvo's DW1000 and DWM1000 UWB IoT modules are revolutionising the agricultural technology space with their ultra-precise positioning systems. The DW1000 IC, which is compliant with IEEE802.15.4-2011 UWB standards, is integrated into a wireless transceiver module that offers many benefits to the Agritech innovation.


One of the most significant benefits of the DW1000 module is its ability to provide real-time location systems (RTLS) with precision up to 10 cm indoors. This precision is essential in agriculture, where knowing the exact location of objects like crops or equipment can lead to increased efficiency and cost reductions.


Additionally, the DW1000 module also offers high data rate communications of up to 6.8 Mb/s. This feature is crucial in agriculture, where real-time data can make a significant impact on decision-making processes.


The DW1000 module's excellent communication range of up to 300 m is also a major advantage. This capability is thanks to coherent receiver techniques and allows for reliable communications in high fading environments. The short packet durations of the module also support high tag densities, allowing for the monitoring of multiple objects simultaneously.


The module's low power consumption is another significant benefit, as it allows for operation from batteries for extended periods. This capability reduces the need to replace batteries and lowers system lifetime costs. Moreover, the module's small physical size allows for the implementation of cost-effective solutions in RTLS and WSN. The integrated antenna also simplifies product implementation, eliminating the need for RF design.
