D22-LS Two probes LoRaWAN Waterproof /Outdoor Temperature Sensor

The Dragino D22-LS is a LoRaWAN® dual-channel temperature sensor designed for reliable long-range temperature monitoring in outdoor and industrial environments. It converts temperature readings from two DS18B20 probes into LoRaWAN wireless data and transmits them to an IoT platform via a LoRaWAN gateway.

With ultra-long-range communication, low power consumption, and high interference immunity, the D22-LS is ideal for applications requiring continuous and accurate temperature tracking. It supports temperature alarms, data logging during network outages, BLE configuration, and wireless OTA firmware updates. Powered by a solar panel with a Li-ion battery, the D22-LS is built for long-term, maintenance-free operation of up to 5 years, even in remote locations.
