D20-LS LoRaWAN Waterproof/Outdoor Temperature Sensor

The Dragino D20-LS is a long-range LoRaWAN temperature sensor designed for continuous outdoor and industrial temperature monitoring. It uses a DS18B20 temperature probe (2-meter cable) to accurately measure temperatures from -55°C to +125°C, and wirelessly uploads the data to an IoT platform via a LoRaWAN gateway.

The D20-LS is powered by a solar panel with a 3000mAh Li-ion rechargeable battery, making it ideal for maintenance-free, long-term deployments. It supports temperature alarms, data logging, BLE configuration, and wireless OTA firmware updates, enabling simple setup and reliable remote management.

With its IP66 waterproof enclosure, the D20-LS performs reliably in harsh outdoor environments such as agriculture fields, cold chain facilities, and industrial sites.
