S31B-NB - NB-IoT Temperature and Humidity Sensor with SIM Card

The Dragino S31B-NB is a Temperature and Humidity Sensor for NB-IoT. 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 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.

This version has 1NCE SIM card pre-installed and is configured to send data to DataCake. You just need to create the sensor type in DataCake and switch it on. Then you will see the measured values in DataCake on your computer or smartphone.

The SIM card has 500MB data volume and is valid for 10 years. The 1NCE NB-IoT service has coverage in most European countries. The current coverage can be checked on the website of 1NCE.

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

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