The Milesight EM410-RDL-EU868/US915-EA is an advanced LoRaWAN radar distance and level sensor with external antenna, designed for accurate, non-contact monitoring of liquid levels and suitable solid surfaces in industrial, environmental and smart infrastructure applications.
Using 60 GHz millimeter-wave radar technology, the EM410-RDL measures the distance to a target surface without physical contact, making it particularly suitable for water tanks, wastewater networks, drainage systems, reservoirs and industrial storage facilities.
The sensor provides a measurement range of 0.3 to 12 meters, with accuracy up to ±2 mm and 1 mm resolution under specified measurement conditions.
Its narrow 8° radar beam helps focus measurements on the target surface while reducing interference from surrounding structures and unwanted reflections.
This EU868/US915 LoRaWAN version enables long-range, low-power wireless communication with a compatible LoRaWAN gateway and network server. It supports OTAA and ABP activation, allowing integration into compatible LoRaWAN monitoring systems.
The EA (External Antenna) configuration provides flexibility in antenna placement and installation, particularly in locations where radio signal conditions require careful consideration.
The rugged IP68-rated PVDF enclosure offers protection against water ingress and corrosion, making the device suitable for demanding outdoor and industrial environments. The published immersion condition is up to 1 meter for 48 hours.
Powered by a high-capacity 19,000mAh Li-SOCl₂ battery, the EM410-RDL is designed for long-term operation, with a stated battery life of up to 7 years in LoRaWAN mode, depending on transmission intervals, radio conditions and device configuration.
The sensor supports NFC and Bluetooth configuration, making installation and maintenance convenient. Its built-in 3-axis accelerometer enables tilt detection and installation-related alerts.
Dedicated measurement modes for standard applications, rainwater systems, sewage networks and tanks allow the sensor to be adapted to different monitoring environments.
The Milesight EM410-RDL LoRaWAN EA is a practical solution for water resource management, wastewater infrastructure, smart cities, industrial automation and remote environmental monitoring.
Important: This is the LoRaWAN EU868/US915 version, not the cellular model. A compatible LoRaWAN gateway and network server are required for remote data transmission. The sensor measures distance to the target surface; level calculations depend on the configured installation reference height.
