SynField HN supports exclusively Cloud communication when there is a multi-node network on the field. Specifically, it collects data from the other regional nodes of the network and transmits them to Cloud. SynField HN has 8 connectors for sensors or actuators (electrovalves, start / stop pumps or relay switches) and is the only model that supports the connection with a weather station. Additionally, it features Bluetooth 2.1 interface which enables easy on-site setup/control via a mobile application. SynField HN connects to internet through Wi-Fi, GPRS/EDGE or LoRaWAN networks. It is fully weatherproofed for outdor use and it has a ESD/lightning protection. Finally, it is energy-independent because it has a built-in solar panel and a rechargeable battery.
