D23-LB Three probes LoRaWAN Waterproof /Outdoor Temperature Sensor

The D23-LB is a LoRaWAN-based triple temperature sensor designed for IoT applications requiring precise, long-range temperature monitoring. Equipped with three DS18B20 probes, it measures temperatures from –55 °C to +125 °C with ±0.5 °C accuracy (max ±2.0 °C) and transmits readings via the LoRaWAN v1.0.3 Class A protocol.

The device supports temperature alarms, datalogging, BLE v5.1 configuration, and wireless OTA firmware updates. Powered by an 8500 mAh Li/SOCl₂ battery, it ensures up to 5 years of operation, enclosed in a durable IP66 waterproof housing for outdoor and industrial use.
