The Dragino D22-LB Two Probes LoRaWAN® Waterproof Outdoor Temperature Sensor is a dual-channel industrial temperature monitoring device designed for long-range IoT deployments across India. Built on LoRaWAN® LPWAN technology, the D22-LB 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 high accuracy, this sensor is ideal for industrial automation, cold chain systems, utilities, and infrastructure monitoring. The IP66 waterproof enclosure ensures reliable outdoor performance, while the 8500mAh Li-SOCI2 battery enables up to 5 years of operation. AIoTkart®, as an Authorized Dragino Distributor in India, supplies genuine D22-LB sensors with PAN-India shipping and technical support for industrial and institutional IoT projects.
