The Dragino S31B-LS is a LoRaWAN Temperature and Humidity Sensor for the Internet of Things solution. It precisely measures the surrounding environment's temperature and relative air humidity and then uploads it to the IoT server via LoRaWAN wireless protocol.
The temperature & humidity sensor used in S31B-LS 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.
The LoRa wireless technology used in S31B-LS allows the 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-LS supports the Temperature & Humidity alarm feature, the user can set the temperature alarm for instant notice. S31B-LS supports the Datalog feature, it can save the data when there is no LoRaWAN network and uplink when the network recovers.
S31B-LS supports BLE configuration and wireless OTA update which makes users easy to use.
S31B-LS is powered by a Solar panel + 3000mAh Li-ion battery, designed for long-term use up to 5 years.
Each S31B-LS is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto-connect after power on.
