Parallax's new PING))) ultrasonic sensor provides an inexpensive and 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. -- You will definitely appreciate the activity status LED and the economic use of just 1 I/O pin. The PING))) sensor measures distance using sonar; an ultrasonic pulse is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return. -- Output from the PING))) sensor is a variable-width pulse that corresponds to the distance to the target. Interfacing to BASIC Stamp and Javelin Stamp microcontrollers is a snap. |
