Sigfox IOT Plant MonitorT



This device was designed to measure ground temperatures at different depths (0cm, 5cm, 20cm, 40cm) and send them over periodically (e.g. every hour) to the cloud using the Sigfox network. They can be used to supervise crops growth conditions (e.g. asparagus, potatoes, ...) and estimate the best moment for harvest, or to monitor air temperature and warn for icing conditions. It was developed by EmTroniX in collaboration with RMS.lu.
Controlled by a low power STM32F4XX microcontroller, the hardware integrates a one-wire interface which can read temperatures from up to eight sensors. A GPS module and a 3-axis accelerometer are present on the board for future enhancements or use for other applications.
