Parallax PING))) Ultrasonic Sensor
Parallax PING))) Ultrasonic Sensor by ALSR at Life N Gadget. MPN: ALSROB-001. Hurry! Limited time offer. Offer valid only while supplies last. ultrasonic sensor provides a very low-cost and easy method of distance measurement. This sensor is perfect for any number of applications that
Interfacing to the BASIC Stamp and Javelin Stamp microcontrollers is a snap: a single (shared) I/O pin is use to trigger the Ping sensor and "listen" for the echo return pulse. And the intelligent trigger hold-off allows the PING)))? to work with the BS1! An onboard three-pin header allows the PING))) to be plugged into a solderless breadboard (on a Boe-Bot, for example), and to be connected to its host through a standard three-pin servo extension cable.
