All you need is a Up/Down dounter triggered by two IR sensors getting an IR beam emitted from two IR led's. When beams get intrupted by any person in a sequence, the same will trigger the up/down count of the counter and display the same on the display. IR led's and sensors like TSOP1738 will work fine for the specified range. Cheers

| this is a difficult task, unless you can ensure that 2 or more people don't pass through th doors at the same time. An intelligent camera system could be made to do this, using labview (with some shape detection and movement algorithms) and some acquisition system for example.
