S31-NB NB-IoT Temperature Humidity Sensor
S31-NB NB-IoT Temperature Humidity Sensor
The Dragino S31-NB and S31B-NB are NB-IoT 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 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 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 including TCP, MQTT, and UDP for different application requirements, and supports uplinks to various IoT Servers.
S31-NB / S31B-NB 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).
S31-NB / S31B-NB has the optional built-in SIM card and default IoT server connection version. Which makes it works with simple configure.
