Component Introduction
The HC-SR04 ultrasonic sensor is a device that can measure the distance
to an object by using sound waves. It measures distance by sending out a
sound wave at a specific frequency and listening for that sound wave to
bounce back. By recording the elapsed time between the sound wave being generated and
the sound wave bouncing back, it is possible to calculate the distance between the sonar
sensor and the object.
