Ultrasonic sensor

An ultrasonic sensor is a device that detects the distance to an object by emitting high-frequency sound waves, similar to those beyond human hearing. When the sound waves hit an object, they bounce back to the sensor. The sensor measures the time it takes for the sound waves to return and calculates the distance based on the speed of sound. This technology is commonly used in robotics, parking sensors, and obstacle detection to help machines or vehicles navigate and avoid collisions accurately and efficiently.
