The Dragino D20-LB is a LoRaWAN temperature sensor for Internet of Things solutions. D20-LB has 1~3 temperature sensors. The D20-LB converts the temperature readings into wireless LoRaWAN data and sends it to the IoT platform via the LoRaWAN gateway.
The LoRa wireless technology used in the D20-LB allows the device to send data and achieve extremely long ranges at low data rates. It offers spread spectrum communication with extremely long range and high interference immunity with minimal power consumption.
The temperature sensor used in D20-LB can measure -55°C ~ 125°C with an accuracy of ±0.5°C (maximum ±2.0°C).
D20-LB supports temperature alarm function, user can set temperature alarm for instant notification. D20-LB supports datalog function, can save the data when there is no LoRaWAN network and uplink when the network is restored.
D20-LB supports BLE configuration and OTA wireless update, which makes it easier for users to use.
D20-LB is powered by a 8500mAh Li-SOCI2 battery, designed for long-term use of up to 5 years.
Each D20-LB is pre-installed with a set of unique keys for LoRaWAN registrations. Register these keys on the local LoRaWAN server and the connection will be established automatically after power on.
The difference to the DRAGINO D20-LB (item 217605) lies in the design of the sensor head.
