What I'm trying to do is make a motion detector that will count the number of people in my house (i.e. my roommates and friends).
Get them to wear RFID tags?
Back in the 60s I worked on a project for counting people upstairs in a bus. It used pressure pads on the stairs. The counting bit is no problem, getting the correct sensor information is.This is one of those projects that sounds easy until you come to do it.

i wanted to make something that would recognise if someone was walking in or out of a room. it was just two lasers on ether side of the door way, pointing at two photocells. when someone would walk in one beam would be blocked then the other. depending on which one was blocked first you could tell if they were going in or out
Was that for safety purposes?
Thanks everyone for your inputs. I like the laser option, but I wander if a two garage door sensors would do the trick?
