The sensor and the Quarky have the following pins: This sound wave is higher in frequency than the normal human hearing range. Ultrasonic sensors have now found their way into a wide range of applications and industries. It works by emitting a sound wave that travels through the air and bounces back to the sensor if it encounters an obstacle or object and thus calculates the distance by measuring time lapses between the sending and receiving of the ultrasonic pulse. It is one of the most reliable ways to sense proximity and detect a target. It is a demanding instrument in robotics as well as for industrial purposes.
