Ultrasonic Sensor module used for measuring distance, object, motion etc. It can be used with microcontroller.
This module transmit eight number of 40 KHz square wave pulses. Which is called Sonic Blast. It automatically detects the pulse whether it receives the receiving signal. A Sonic Blast Transmitting by Trigger pin and returning signal received by Echo Pin.
