The ultrasonic sensor ranging module HC-SR04 offers excellent range accuracy and fairly stable readings at very low cost. It requires two digital I/O pins (an output pin and an input pin) to interface with it. Since ultrasonic sensor uses sonar to determine the distance to an object, its operation is not affected by sunlight, spotlight and object's surface color which will affect the readings of any infrared distance sensors. However acoustically soft materials such as clothes can be difficult to detect.

HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit. The basic principle of work : 

(1)    Using IO trigger for at least 10us high level signal,
(2)    The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.
(3)    If the signal back, through high level, time of high output I/O duration is the time from sending ultrasonic to returning. Test distance = (high level time×velocity of sound (340m/s)) / 2
