D20S-LB LoRaWAN Temperature Sensor

The D20S-LB is a LoRaWAN temperature sensor designed for IoT applications requiring reliable long-range and low-power data transmission. It uses a DS18B20 probe (2 m) to measure temperatures from –55 °C to +125 °C with an accuracy of ±0.5 °C (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. Its 8500 mAh Li/SOCl₂ battery ensures up to 5 years of operation, while the IP66 waterproof enclosure makes it suitable for outdoor or industrial use.
