MDS120-LS LoRaWAN Microwave Radar Sensor

The Dragino MDS120-LS is a LoRaWAN-based 60 GHz microwave radar distance sensor designed for reliable distance and level measurement in challenging environments. Unlike ultrasonic or LiDAR sensors, microwave radar performs accurately in dusty, humid, or condensation-heavy conditions, even when water or debris is present on the sensor surface. The MDS120-LS is solar-powered with a built-in Li-ion battery, making it ideal for long-term outdoor deployments.
