MR-XX-CB/CS
NB-IoT/LTE-M Microwave Radar Distance Sensor
The Dragino MR-03/12/25-CB/CS is a NB-IoT/LTE-M Microwave Radar distance Sensor for Internet of Things solution. It uses 80Ghz Microwave to detect the distance between sensor and diferent objects. Diferent 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-03/12/25-CB/CS 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-03/12/25-CB/CS supports different uplink methods including MQTT, MQTTs, UDP, TCP or CoAP for different application requirement, and support uplinks to various IoT Servers.

Application guide
Choose the airflow range by deployment scenario
0–5 m/s range
Cold Storage & Display Cases
For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.
0–10 m/s range
HVAC Ducts & AHU Verification
For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.
0–30 m/s range
Industrial Ventilation & Fan Outlets
For main duct airflow, fan outlets, compressed air systems, and industrial ventilation monitoring.
How it works
Remote airflow monitoring via LoRaWAN
Deploy AirFlow-LN at critical airflow points, transmit measurements through a LoRaWAN gateway, and use platform data to detect weak airflow, filter problems, or abnormal ventilation conditions earlier.
- AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
- LoRaWAN gateway receives data from distributed sensors across the site.
- Cloud platform visualizes trends and helps trigger maintenance decisions.
