This device can be used to remotely monitor crops growth conditions (e.g. asparagus, potatoes, grapes…) and estimate the best moment for harvest. It can also be configured to issue warning of icing conditions.
To do so, it measures air or 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.
