Arduino edge control improves smart farming

Arduino launched its new board, Arduino Edge Control, which is a remote monitoring and control solution optimized for outdoor environments. In an interview with EEWeb, CEO Fabio Violant mentioned how Arduino Edge Control has been applied in precision agriculture and other applications where intelligence is essential. Energy can be provided by a solar cell or conventional DC power source, and the panel can deploy artificial intelligence at the edge. It can be expanded with 2G / 3G / CatM1 / NB-IoT modems, LoRa connection, Sigfox, Wi-Fi / Bluetooth connectivity and remote management via Arduino or external cloud. The board is designed to use the least amount of energy and keep only the essential devices running related to external interruptions [for example, from watermark sensors] And RTC [for interval time wakeup]Violant said. “Thanks to these solutions, the board can work for up to two years using a 12-V / 4-Ah battery in a real application. In addition to the above, the panel contains a solar panel battery charger, which allows charging of 12-volt lead batteries, which extends the life Effectively forever. ” Smart Agriculture Arduino Edge Control can deliver a variety of external solutions such as sensors and motors to control trigger valves, which are widely used in agriculture, as well as provide intelligent real-time data processing to reduce the risks associated with various activities. Violante said the processor used in the Arduino Edge Control is nRF52840, the same as the Nano BLE, and is compatible with several AI libraries, such as TensorFlow micro. The nRF52840 SoC is a member of the nRF52 Series SoC. It provides available memory capacity for both flash and RAM, which are basic requirements for such challenging applications. The nRF52840 is built around a 32-bit ARM Cortex-M4 CPU, with a 64MHz floating point module operating. The ARM TrustZone CryptoCell cipher module is embedded on the chip and provides a wide range of cryptographic options that operate highly efficiently and independently of the CPU. Real-time data about weather conditions, soil quality and crop growth, all of which can be of value to a farming business, provides control over crop efficiency and yield. Violante demonstrated how Arduino Edge Control can increase crop quality and reduce human error by automating processes such as irrigation, fertilization or pest control.

Example of a typical implementation of a two-board solution from Arduino MKR. “Due to the professional nature of this forum, we have decided not to put onboard sensors that will suffer from the final setup for customers to use,” Violante said. “Instead, we provided enough I / O to allow customers to connect to their favorite external sensors, weather stations, etc.” During development, we had various collaborations to validate and test Edge Control, ”he added.“ One of them is with a European company (Challenge Agriculture) specializing in precision agriculture and irrigation. There are now various active projects underway to deploy Edge Control to the field. Figure 2: Technical specifications for specific Arduino Edge Control applications include automated greenhouses, that is, manage moisture and temperature automatically to ensure the best environment for growing crops, reduce carbon emissions, and increase economic returns. This panel is mainly aimed at fixed applications; therefore, the GPS module was considered Virtualization is redundant, as the board’s position can be recorded during installation, “Violante said. “However, we have a compatible GPS shield that can be attached to this board.” The inclusion of the Arduino MKR GPS Shield allows for optimal crop rotation and geospatial data acquisition. Another application is hydroponics, that is, the growth of plants without soil that requires special care to maintain the conditions necessary for optimal growth. Another application that Arduino highlights is fungi growth that requires optimum temperature and humidity. The numerous sensors and connection options provide a control method that can reach great heights thanks to open source programming.
