EM500-UDL LoRaWAN Ultrasonic Distance/Level Sensor 10 m

The EM500-UDL provides highly accurate distance measurement for a variety of applications in harsh environments such as flood monitoring, wastewater management, fill level monitoring in grains or fertilizers. The measurement is based on ultrasonic waves transmitted and reflected by nearby objects.

EM500-UDL is designed for object level or distance detection in harsh environments and for data transmission using LoRaWAN® technology. With this low power consumption technology, EM500-UDL can work for up to 10 years with a 19000 mAh battery. Combining with the Milesight LoRaWAN® gateway and Milesight Development Platform solution, users can manage all sensor data remotely. EM500-UDL is widely used for outdoor applications such as liquid level monitoring, water tank level monitoring, etc.
