D22-LB Two probes LoRaWAN Waterproof /Outdoor Temperature Sensor

The D22-LB is a LoRaWAN-based dual temperature sensor designed for IoT applications requiring long-range, low-power temperature monitoring. It uses two DS18B20 probes to measure temperatures from –55 °C to +125 °C with an accuracy of ±0.5 °C (max ±2.0 °C), transmitting data via LoRaWAN v1.0.3 Class A.

The device supports temperature alarms, datalogging, BLE v5.1 configuration, and wireless OTA firmware updates. Powered by an 8500 mAh Li/SOCl₂ battery, the D22-LB provides up to 5 years of operation within an IP66 waterproof enclosure, ideal for outdoor and industrial use.
