IoT temperature and relative humidity sensor with a NB-IoT transmission unit.

Reference
S31-NB
Available (19 Items)

Dragino's S31-NB temperature-humidity sensor lets you measure temperature and humidity accurately and communicate the data over a NB-IoT 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 4 years, which may vary depending on the environment, the quality of the network and the recording interval.

The transmitter is sold without a SIM card and without any subscription.

The S31-NB 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.
