MR-03-NB -- Dragino NB-IoT Microwave Radar Distance Sensor

The Dragino MR-03-NB is a NB-IoT Microwave Radar distance Sensor for Internet of Things solution. It uses 80Ghz Microwave Radar to detect the distance between sensor and different objects. Different from ultrosonic or Lidar measurement. Microwave Radar is more reliable for condensation / dusty environment. It can sense correct distance even there is water or think dust on top of the sensor.
 
The MR-03-NB can be applied to scenarios such as horizontal distance measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, etc.
 
MR-03-NB supports BLE configure and wireless OTA update which make user easy to use.
 
MR-03-NB supports different uplink methods include TCP, MQTT, UDP, MQTTs or CoAP for different application requirement. and Support Uplinks to various IoT Servers.
 
MR-03-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
