LoRaWAN Dragino D20-LB outdoor temperature sensor

Dragino D20-LB is a LoRaWAN temperature sensor for IoT solution. The D20-LB converts the temperature readings into LoRaWAN wireless data and sends it to the IoT platform through the LoRaWAN gateway.

The LoRa wireless technology used in the D20-LB allows the device to send data over extremely long distances at low data rates. It provides communication with an ultra-wide range of extended spectrum and high resistance to interference, minimizing current consumption.

The temperature sensor used in the D20-LB can measure from -55°C to 125°C with an accuracy of ±0.5°C (max. ±2.0°C).

D20-LB supports temperature alarm function, user can set temperature alarm for instant notification. D20-LB supports data logging function, it can save data when LoRaWAN network is down and transmit data when network is restored.

D20-LB supports BLE setup and wireless OTA update, which makes user’s use easier.

The D20-LB is powered by an 8500 mAh SOCI2 lithium-ion battery, which is designed for long-term use of up to 5 years.

Each D20-LB is preloaded with a set of unique LoRaWAN registration keys. Register these keys with your local LoRaWAN server and it will connect automatically after power on.
