Welcome to AAC.

You placed your post onto a thread that is nearly a year old - http://forum.allaboutcircuits.com/showthread.php?t=18154 - and so nobody is going to be current with the project.

We can't do the project for you - what ideas do you have for detecting the people and counting the number of them?

 

That will do what you describe, but it will not tell you the number of people in the room. For example, people may enter in pairs and leave singly.

how can we apply that logic?how can we integrate 2 detectors?where should the counter display its result?
