[Need help] Rectangular Area Detection

[my2k]

Hi all,

I am new in this forum and I wish to find help.

I have a rectangular area and I am looking for a set of components (i.e Sensors ) to detected if the object inside this area or not.:roll:

The output of the circuit should be suitable for a programming language.:-|

I want to connect and program the circuit to a basic stamp parallax training kit.

Any idea, please help!

Thanks in advance.

Sensors depend on object parameters. Use a video camera; there are programs that can extract the needed information from the video signal.
