S31B-CB - NB-IoT/LTE-M Temperature and Humidity Sensor

The Dragino S31B-CB is a Temperature and Humidity Sensor for NB-IoT and LTE-M. It is used to measure the surrounding environment temperature and relative air humidity precisely, and then upload to IoT server via NB-IoT/LTE-M network.

The temperature & humidity sensor used in S31B-CB 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.

You can use various IoT Servers and different uplink methods including MQTT, MQTTs, UDP and TCP. 

The sensor node uses Quectel BG95-NGFF Multi-band LTE Cat M1/Cat NB2 module with GPS which can be used in most European countries. It has a card slot for an NB-IoT/LTE-M SIM card. 

This device supports BLE for easy configuration and wireless OTA to update the firmware.

S31B-CB is powered by 8500mAh Li-SOCI2 battery for many years of use. It has an external antenna and an IP66 enclosure.
