Water shortage is an ever-increasing challenge that must be addressed with sustainable solutions. Our IoT-based soil monitoring solution targets precision agriculture use cases and promotes a sustainable use of water. It is a solution based on long-range, low-power communication technologies and off-the-shelf hardware that: i) is compliant with different sensing probes, and ii) has a protective enclosure allowing underground operation and further protection from theft, machinery damage and harsh environment conditions. This demo paper presents our prototype based on the LoRa/LoRaWAN and NB-IoT technologies. Preliminary tests show that our prototype is water resistant and can communicate up to 1.7km while buried 10cm underground.
