S31-LS - Solar Powered LoRaWAN Temperature & Humidity Sensor

The Dragino S31-LS 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 S31-LS 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.

S31-LS supports temperature and humidity alarm feature, user can get alarm for instant notice.

S31-LS supports BLE and LoRaWAN remote configure which makes it very easy to adapt the device. It also supports wireless OTA to update the firmware.

S31-LS is powered by a rechargeable battery with solar cell and allows continuous use.

Each S31-LS is pre-load with a set of unique keys for LoRaWAN registration, register these keys to local LoRaWAN server and it will auto connect after power on.
