ultrasonic sensors
Ultrasonic sensors detect objects and measure distances by emitting high-frequency sound waves beyond human hearing. When these sound waves hit an object, they bounce back to the sensor. The sensor measures the time it takes for the echoes to return, and from this, it calculates how far away the object is. This technology is commonly used in parking sensors, robotics, and industrial automation to enable machines to navigate and avoid obstacles accurately without physical contact. Ultrasonic sensors are valued for their simplicity, reliability, and ability to work in various environmental conditions.
