[S31B-LB] LoRaWAN Temperature & Humidity Sensor

The Dragino S31B-LB is a LoRaWAN Temperature and Humidity Sensor for Internet of Things solution. It is used to measure the surrounding environment temperature and relative air humidity precisely, and then upload to IoT server via LoRaWAN wireless protocol.

The temperature & humidity sensor used in S31B-LB 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.

The LoRa wireless technology used in S31B-LB allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

S31B-LB supports Temperature & Humdity alarm feature, user can set temperature alarm for instant notice. S31B-LB supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.

S31B-LB supports BLE configure and wireless OTA update which make user easy to use.

S31B-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each S31B-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.
