PING))) Ultrasonic Sensor

If you want to measure distance in your electronics project, I strongly recommend the PING))) ™ Ultrasonic sensor from Parallax. 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.

Say tuned for instructions on how to connect the PING))) sensor to your .NET project! ;-)
