    Ultra sonic sensor distances?

    I want to make a BMW style ultra sonic sensor diagram. (The one with the colors extending from the front and rear of the car). But to do this i need to get the distance of the obstacle from the ultra sonic sensors...

    Does anyone have a controller/encoder that will give this information to me? or know how i could find out the distance?

    Thanks

    do a ebay search for parktronic. On that one there are little bars the light up as it goes and you might have a better chance of tapping into the led that would light up for each bar and interfacing with that.

    yeah i did think of that, i was looking for a more... specific distance. Like exactly 1.2m (still aware of error tolerances).

    If all else fails i'll have to do that!

    There are all kinds of kits and circuits available on the web. You need an ultrasonic driver/receiver and a processor to measure the time between the outgoing ping, and the received ping.

    I remember once upon a time, many people used the guts of a Polaroid instant camera.
