MR-XX-LB LoRaWAN Microwave Radar Distance Sensor
The Dragino MR-XX-LB/LS is a high-precision LoRaWAN Microwave Radar Distance Sensor designed for reliable performance in challenging environments. Using advanced 80 GHz microwave radar technology, it accurately measures the distance between the sensor and nearby objects. Unlike ultrasonic or LiDAR methods, microwave radar is highly resistant to condensation, moisture, and heavy dust, ensuring stable and accurate readings even when the sensor surface is wet or contaminated.
The MR-XX-LB/LS is ideal for a wide range of applications, including:
-
Horizontal distance measurement
-
Parking and vehicle detection systems
-
Object proximity and presence sensing
-
Smart waste bin monitoring
-
Robot navigation and obstacle avoidance
-
Automated control systems
-
Sewer and harsh-environment monitoring
Powered by LoRaWAN long-range wireless communication, the device delivers exceptional transmission distance, strong interference immunity, and ultra-low power consumption—making it suitable for remote or hard-to-access installations.
The sensor also features BLE configuration and wireless OTA updates, providing a simple and user-friendly setup and maintenance experience.
Designed for long-term field deployment, the MR-XX-LB/LS can operate on an 8500 mAh Li-SOCl₂ battery or solar + Li-ion battery system, supporting up to 5 years of continuous use depending on configuration and reporting frequency.
