S31B LPWAN NB-IoT Outdoor Temperature and Humidity Sensor
The Dragino S31 is an NB-IoT Temperature and Humidity Sensor for the 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 S31 is SHT31, which is fully calibrated, linearized, and temperature compensated digital output from Sensirion, it provides strong reliability and long-term stability. The SHT31 is fixed in a waterproof anti-condensation casing for long-term use.
S31B supports different uplink methods include TCP, MQTT, UDP, and CoAP for different application requirements.
S31 is powered by an 8500mAh Li-SOCI2 battery, It is designed for long-term use up to several years. (Real-world battery life depends on the use environment, update period. Please check the related Power Analyze report).
