Parallax PING))) Ultrasonic Distance Sensor (28015) Digitally controlled knobs for finePING))) Ultrasonic Distance Sensor Overview: Our PING))) ultrasonic sensor provides an easy method of distance measurement. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. Interfacing to a microcontroller is a snap. A single I O pin is used to trigger an ultrasonic burst (well above human hearing) and then listen for the echo return pulse. The sensor measures the time
