The Dragino S31-NB and S31B-NB are 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 S31-NB / S31B-NB is SHT31, which is fully calibrated, linearized, and temperature compensated digital output from Sensirion, it provides a strong reliability and long-term stability. The SHT31 is fixed in a waterproof anti-condensation casing for long term use.
S31-NB / S31B-NB supports different uplink methods include TCP, MQTT, UDP for different application requirement, and support uplinks to various IoT Servers.
S31-NB / S31B-NB is powered by 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 and uplink method. Please check related Power Analyze report).
S31-NB / S31B-NB has the optional build-in SIM card and default IoT server connection version. Which make it works with simple configure.
