The MULTICOMP PRO Ultrasonic Sensor, Transceiver operates by emitting ultrasonic waves at a frequency of 58kHz. When these waves encounter an object, they are reflected back to the sensor. The sensor then calculates the distance to the object based on the time delay between sending the wave and receiving the echo.
