D22-LB/LS – LoRaWAN Waterproof Temperature Sensor (2 probes) – Dragino
General Description
Dragino 's D22-LB/LS is a LoRaWAN temperature sensor designed for outdoor environments. It is equipped with two DS18B20 probes for simultaneous measurement of two temperature points with high accuracy. Its long-range LoRaWAN connectivity and low power consumption make it an ideal solution for industrial or agricultural applications.
The D22-LB version integrates an 8500mAh Li-SOCI2 battery , while the D22-LS model works with a solar panel and a 3000mAh Li-ion battery , guaranteeing an autonomy of up to 5 years. The sensor offers Bluetooth configuration, OTA update and a datalog function for measurement continuity even without a network.
