HC-SR04 HC-SR04P Ultrasonic Module Distance Measuring Sonar Sensor 3 V-5.5 
Description
The HC-SR04p ultrasonic sensor uses sonar to determine distance.  It gives excellent non-contact range detection (2cm-400cm or 1’-13’) with high accuracy and stability in one inexpensive component. With only four pins (Vcc, trigger, echo, and ground, this sensor is very easy to set up and use for range-finding projects like a sonic tape measure or an obstacle avoidance mechanism for a robot.

This sensor works by sending a pulse to the trigger pin. Once triggered, the sensor will send out a pulse of sound and listen for the echo. When it detects the echo, it will output a pulse equal in length to the time it took to hear the echo. The distance can then be calculated as half the time to echo divided by the speed of sound (Pulse Time / 2*Speed of Sound).
