i am currently building a pit lane like this
I have ssd PB pro and would like to use phidgets to detect cars in the pits. I wanted to have a sensor in each of the 4 (possibly extended to 6) bays so that the car would simply stop over it to refuel. This also means that a car could not refuel in any bay but his own. I would also like to have start lights although i may do this using a lpt port.
So my question....
what card should i be looking at? - i do not want to spend too much money
what sensors are required to detect not only the car but its id?
thanks alot
