Ultrasonic sensors measure object separation distance using ultrasonic waves.
The sensor head emits an ultrasonic wave and receives the wave reflected back from the target. Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception. It generates high-frequency sound (above the human hearing range) waves. HC SR04 module provides for a detection range of 2-400cm, contactless measurement! The modules includes ultrasonic transmitter, receiver and a control circuit.
