Long-Range Radar Distance & Level Measurement for Harsh Environments
The Dragino MR-25-LB2 is a professional LoRaWAN® Microwave Radar Distance Sensor designed for accurate distance and level monitoring in demanding outdoor and industrial environments. Using advanced 80GHz FMCW radar technology, the sensor provides highly reliable measurements even in conditions where ultrasonic and LiDAR sensors may struggle, such as dust, condensation, steam, fog, rain or dirty environments.
The MR-25-LB2 offers a measurement range from 200 mm to 25 meters, making it suitable for tank level monitoring, wastewater systems, smart waste bins, parking management, sewer monitoring, industrial automation and proximity detection applications. The narrow 7.6° beam angle allows accurate measurements even in confined spaces and deep tanks.
Powered by an 8500mAh Li-SOCl₂ battery, the sensor is designed for ultra-low-power operation and can provide years of autonomous field operation. It supports Bluetooth v5.1 configuration, LoRaWAN remote configuration, and wireless OTA firmware upgrades, simplifying deployment and maintenance.
With LoRaWAN® Class A communication, excellent RF sensitivity and industrial-grade construction, the MR-25-LB2 is an ideal solution for long-range distance and level monitoring projects requiring reliability and low maintenance.
