S31 NB-IoT LTE CAT-M Temperature Humidity Sensor
S31 NB-IoT LTE CAT-M Temperature Humidity Sensor
The Dragino S31 and S31B are NB-IoT and LTE CAT-M Temperature and Humidity Sensor for Internet of Things solutions. It is used to measure the surrounding environment temperature and relative air humidity precisely, and then upload to the IoT server/cloud via NB-IoT and LTE CAT-M network.
The temperature & humidity sensor used in S31 / S31B 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 / S31B supports different uplink methods including TCP, MQTT, and UDP for different application requirements, and supports uplinks to various IoT Servers.
S31 / S31B 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, and uplink method. Please check the related Power Analyze report).
