    S31-CB NB-IoT/LTE-M Outdoor Temperature and Humidity Sensor

    The Dragino S31-CB and S31B-CB are NB-IoT/LTE-M Temperature and Humidity Sensors for Internet of Things solutions. It is used to measure the surrounding environment temperature and relative air humidity precisely, and then upload to IoT server via NB-IoT or CAT-M1 network.

    The temperature & humidity sensor used in S31-CB / S31B-CB 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.

    S31-CB / S31B-CB supports different uplink methods include MQTT, MQTTs, TCP, UDP or CoAP for different application requirements, and support uplinks to various IoT Servers.

    S31-CB / S31B-CB 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).
