seems like a very late reply but still would want to help .. !
the ultrasonic sensor can be easily interfaced with a microcontroller..using the cheap modules no external circuitry is required and you get very accurate results… you can refer the datasheet for more info.
The one i used was HC-SR 04 ..just google the data sheet..quite simple to implement
