Description
The Ultrasonic Sensor is a distance-measuring sensor that uses high-frequency sound waves to detect objects and calculate how far away they are. It works by sending an ultrasonic pulse and measuring the time it takes for the echo to return after bouncing off an object.
Ultrasonic sensors are widely used in robotics, obstacle avoidance systems, parking sensors, automation projects, and many DIY electronics applications because they provide accurate, contactless distance measurement.
