https://www.aiotkart.com/web/image/product.template/17646/image_1920?unique=fda5c53

The Dragino D22-LS Two Probes LoRaWAN® Waterproof Outdoor Temperature Sensor is a solar-powered industrial IoT temperature monitoring solution designed for reliable long-range outdoor deployments. Built on LoRaWAN® LPWAN technology, the D22-LS converts real-time temperature readings from two DS18B20 probes into secure wireless data and transmits it to an IoT platform via a LoRaWAN® gateway.

With a wide measurement range of -55°C to +125°C and ±0.5°C accuracy (max ±2.0°C), the D22-LS is ideal for multi-point temperature monitoring in industrial facilities, cold storage systems, agriculture fields, and infrastructure projects. The IP66-rated waterproof enclosure ensures stable operation in harsh environmental conditions.The D22-LS variant is powered by a solar panel combined with a 3000mAh Li-ion rechargeable battery, making it suitable for remote and off-grid installations with long-term autonomous operation of up to 5 years depending on configuration.

AIoTkart® supplies genuine Dragino LoRaWAN® sensors across India with integration support for industrial IoT deployments.
