Sigfox sensor for temperature and humidity monitoring

Development of a sensor (hardware and firmware) for measuring temperature and humidity, which sends data to the server via the Sigfox network on a regular basis. The transmission period is configurable using a Sigfox downlink message (sent from the network to the device). An important requirement was low power consumption so that the device could operate for several years on a single AA battery without the need for replacement.
