Dragino S31B-NB-GE NB-IoT Outdoor Temperature and Humidity Sensor hub-lorawan and a large capacitor shouldThe Dragino S31B NB GE is a NB IoT Temperature and Humidity Sensor for Internet of Things solution. It is used to measure the surrounding environment temperature and relative air humidity precisely, and then upload to IoT server via NB IoT network. The temperature & humidity sensor used in S31B NB is SHT31, which is fully calibrated, linearized, and temperature compensated digital output from Sensirion, it provides a strong reliability and long term
