Solar panel powered LoRaWAN RTU for SDI-12 sensors - TBS12S

TBS12S is a solar panel powered outdoor RTU fully LoRaWAN 1.02 compliant. It has been designed to cope with applications where SDI-12 maximum range is a limitation by leveraging the long range capability of LoRa. TBS12S is delivered within its IP67 rated aluminium die cast housing along with a fixture to tie it to a pole.

It is powered through a rechargeable battery supplied by an integrated solar panel. TBS12S is an upgraded version of TBS12B for applications that are more power demanding (typically when multiple SDI-12 sensors need to be deployed on the same spot).

Its connector allows plugging directly one SDI-12 sensor or a junction box would multiple SDI-12 sensors need to be locally deployed. The embedded LoRa modem supports both low (433/470MHz) and high (868/915MHz) LoRa radio bands, which makes TBS12S suitable to be used anywhere without having to replace the RF board.

TBS12S is deployed as a unique node into a typical LoRaWAN network architecture, sending its packets to the gateway that relays them to the LoRaWAN server over a TCP/IP connection:
