D20S-LS LoRaWAN Waterproof/Outdoor Temperature Sensor

The Dragino D20S-LS is a long-range LoRaWAN temperature sensor designed for reliable outdoor and industrial temperature monitoring. It uses a DS18B20 stainless-steel temperature probe (2-meter cable) to accurately measure temperatures from -55°C to +125°C, and wirelessly transmits the data to an IoT platform via a LoRaWAN gateway.

The D20S-LS is powered by a solar panel with a 3000mAh Li-ion rechargeable battery, enabling maintenance-free, long-term operation. It supports temperature alarms, data logging, BLE configuration, and wireless OTA firmware updates, making deployment and remote management simple and efficient.

With an IP66 waterproof enclosure and a rugged stainless-steel probe, the D20S-LS is ideal for harsh environments such as cold storage, agriculture fields, pipelines, and industrial facilities.
