A short ultrasonic pulse is transmitted at the time 0, reflected by an object. The senor receives this signal and converts it to an electric signal. The next pulse can be transmitted when the echo is faded away. This time period is called cycle period.
VCC is the power supply for HC-SR04 Ultrasonic distance sensor which we connect the 5V pin on the Arduino.. Trig (Trigger) pin is used to trigger the ultrasonic sound pulses. Echo pin produces a pulse when the reflected signal is received. The length of the pulse is proportional to the time it took for the transmitted signal to be detected. GND should be connected to the ground of Arduino.

2020-11-07· How the HC-SR04 works. The HC-SR04 makes it like the bat: it emits an ultrasonic signal and evaluates the echo. The distance can then be calculated via the flight time of the signal and the speed of sound. For this purpose, the module has an ultrasonic transmitter, which is marked with a “T” on the module. Next to it, marked with “R ...
