Milesight EM500-UDL LoRAWAN Ultrasonic Distance & Level Sensor

As is known, ultrasound is high-pitched sound waves with frequencies higher than the audible limit of human hearing, and ultrasonic sensor will emit short ultrasonic waves, then receive them when they are bounced back. Based on the travel time of ultrasonic waves, we can calculate the distance between the transceiver and the surface of the target. Milesight EM500-UDL LoRAWAN Ultrasonic Distance/Level Sensor provides highly accurate distance measurement for a variety of applications in harsh environments like flood monitoring, wastewater management, fill level monitoring in grains or fertilizer. The measurement is based on ultrasonic waves transmitted and reflected back from nearby objects.
