MDS200-NB NB-IoT Microwave Radar Distance Sensor Relay Modules Also included is a roundMDS200 NB NB IoT Microwave Radar Distance Sensor The Dragino MDS200 NB is an NB IoT Microwave Radar distance Sensor for the Internet of Things solution. It uses a 24Ghz Microwave Radar to detect the distance between the sensor and different objects. Different from ultrasonic or Lidar measurement. Microwave Radar is more reliable for condensation dusty environment. It can sense correct distance even if there is water or dust on top of the sensor. The
