Description
The Dragino D22-LB is a LoRaWAN outdoor temperature sensor designed for IoT solutions. It measures the temperature of air, liquid, or solids from –55 °C ~ 125 °C with an accuracy of ±0.5 °C (max. ±2.0 °C) and includes two waterproof sensor cables.
The D22-LB uses LoRaWAN technology to send the temperature information, allowing for ultra-long-range spread spectrum communication and high interference immunity while minimizing current consumption.
The D22-LB supports a temperature alarm, wherein a user can set an alarm for instant notice at a certain temperature.
D22-LB supports BLE configuration and wireless OTA update for ease of use. D22-LB is powered by an 8500 mAh Li-SOCl₂ battery, designed for long-term use of up to 5 years.
Each D22-LB comes preloaded with a set of unique keys for LoRaWAN registrations, and registering these keys to a local LoRaWAN server will cause it to automatically connect after powering on.
