Hi there,
i m currently trying to come out with a project as below
i m trying to use a USB webcam to detect any movement
i plan to implement this into a parking system to detect wether the parking is available
is Java programming suitable for a system like that?
becuz i m running on a very low budget(how much can a student spend possible on his project) mayb sum1 can suggest me with a better h/w ?
i have considered using LED to show status of the availability but i m not sure what to use to sensor it..
any help will be appreciated a lot

Create a unique signal, emit it, watch for it, based on signal strength/
delay/whatever display whether there's a lack of space available.
Couple experiments to try:

hi there,
thx for the fast reply
but i notice is all very electronic engineering is it?
i m currently a networking student..
as for my idea which is USB webcam to detect movement with php programming is it possible?

So you have no electronics background so you're looking for off the shelf components so as to build your project. You want to do sensor monitoring but keep focusing on a camera, which you really don't need. You in essence need to detect existence of a vehicle. The camera will be good for detecting motion. Have you investigated various security equipment available? Get an Ultrasonic detector and hook it up to a GPIO board, which is linked to your PC. The GPIO board can monitor multiple sensors, not just one. The only electronics required then would be wiring the harnesses. Though you could build an electronic circuit using a PIC but you can find the embedded board. Try www.digikey.com or www.mouser.com or a company like that!
An IR LED and IR phototransistor will do for the car detection.

You can look on http://www.ftdichip.com/ for creating a parallel or serial to USB interface.

here's the link http://sourceforge.net/projects/phpmotiondetect/
Since that detects any sort of motion then takes pictures, you would need to look at the pictures to be sure if there was a car in the bay.
In a project like this, you would also need sensors that indicate for sure whether there is a car. A program can then scan the lot and report the number of free spaces etc.
