PING)))™ Ultrasonic Distance Sensor

Measures from 2 cm to 3 m

Perform measurements between moving or stationary objects with Jameco's selection of PING ultrasound distance sensors. Perfect for a variety of applications, Parallax's ultrasonic sensor provides a very low-cost and easy method of distance measurement. Whether you want to use these devices in security systems or as an infrared replacement - or just a fun robotic - these distance sensors will satisfy. You will definitely appreciate the activity status LED and the economic use of just one I/O pin.

Naturally, robotics applications are very popular but you'll also find this product to be useful in security systems or as an infrared replacement if so desired. You will definitely appreciate the activity status LED and the economic use of just one I/O pin. Get the most out of your ultrasonic sensor with the PING))) Mounting Bracket kit that includes a servo and hardware to securely mount the sensor and allow it to perform 180° sweeps of its environment.

The Ping sensor measures distance using sonar; an ultrasonic (well above human hearing) 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 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. Click over to the KickStart Guide to see how to use the PING))) sensor, complete with wiring diagrams and sample code for the BASIC Stamp, Propeller, and Arduino.
