D20-LB LoRaWAN Temperature Sensor

The Dragino D20-LB is a long-range LoRaWAN temperature sensor designed for reliable outdoor and industrial temperature monitoring. It uses a DS18B20 temperature probe (2-meter cable) to measure temperatures from -55°C to +125°C with high accuracy, and securely transmits the data to an IoT platform via a LoRaWAN gateway.

Powered by a high-capacity 8500mAh Li-SOCl₂ battery, the D20-LB is optimized for ultra-low power consumption and can operate for up to 5 years, making it ideal for long-term deployments. The sensor supports temperature alarm, data logging, BLE configuration, and wireless OTA firmware updates, ensuring easy setup and maintenance.

Its IP66 waterproof enclosure allows dependable performance in harsh outdoor environments such as cold chain logistics, and industrial monitoring.
