LoRaWAN S31-LB thermo-hygrometer sensor

Dragino's S31-LB temperature-humidity sensor lets you measure temperature and humidity accurately and communicate the data over a LoRaWAN network. The sensor used is Sensirion's SHT31 with an accuracy of ±0.2 and ±2% RH. The communication unit is waterproof and can be placed outdoors. The sensor, on the other hand, must be placed in a shelter, such as the 7714 shelter from Davis Instruments. 

The sensor is powered by a battery with a life of around 10 years, which may vary depending on the environment, the quality of the LoRa network and the recording interval.

The transmitter is sold without LoRa subscription.

Additionally to all the features of the LSN50v2-S31, the S31-LB can work as a datalogger in case of communication loss with the server. The data collected during the disconnection can be sent in bulk at the reconnection.
