Ultrasonic sensor working principle | How does HC-SR04 Work
Ultrasonic sensor or ultrasound sensor is one of the most used sensor in various projects.It is generally used to find the range/distance of objects.The HC-SR 04 is one of the commonly used ultrasonic sensor.This sensor produces a ultrasound which is reflected back if an object is present in front of it.Then this reflected sound is detected by the receiver of the sensor .The distance is calculated by calculating the time travelled by the sound and velocity of sound.Watch the animation in the video.
