Description
An ultrasonic sensor is an electronic device that uses ultrasonic sound waves to measure distance or detect objects. It works by emitting a high-frequency sound pulse and then measuring the time it takes for the pulse to reflect back from an object. By calculating the time-of-flight, the sensor can determine the distance to the object. These sensors are commonly used in robotics, obstacle detection, level sensing, and proximity applications due to their accuracy, reliability, and ease of integration with microcontrollers and other electronic systems.
