The Dragino D20S-LB is a LoRaWAN Temperature Sensor for Internet of Things solution. D20S-LB will convert the Temperature reading to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.

The LoRa wireless technology used in D20S-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.

The temperature sensor used in D20S-LB can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).

D20S-LB supports temperature alarm feature, user can set temperature alarm for instant notice. D20S-LB supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.

D20S-LB supports BLE configure and wireless OTA update which make user easy to use.

D20S-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each D20S-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.
