LS50V3-D20-LB/ D20S-LB LoRaWAN Waterproof /Outdoor Temperature Sensor

The Dragino D20-LB is a LoRaWAN Temperature Sensor for an Internet of Things solution. D20S-LB is designed for use in Soil or Road. D20-LB/ D20S-LB will convert the Temperature reading to LoRaWAN wireless data and send it to the IoT platform via the LoRaWAN gateway.

The LoRa wireless technology used in D20-LB/ D20S-LB allows devices 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 D20-LB/ D20S-LB can measure -55°C ~125°C with accuracy ±0.5°C (max ±2.0 °C).

D20-LB/ D20S-LB supports the temperature alarm feature, the user can set the temperature alarm for instant notice. D20-LB/ D20S-LB supports the Datalog feature, which can save the data when there is no LoRaWAN network and uplink when the network recovers.

D20-LB/ D20S-LB supports BLE configuration and wireless OTA update, which makes user easy to use.

D20-LB/ D20S-LB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to 5 years.

Each D20-LB/ D20S-LB 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.
