Get them to wear RFID tags?
I find it harder to express logic in English than in Code.
Sometimes an example says more than many times as many words.

It depends on what sort of RFID tag you use.

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.


Was that for safety purposes? Avoid moving the bus when it's top-heavy?

By the way, I think of Tom Cruise as a good example of occupancy detector/avoider in his movie series. So maybe weigh the people as they enter. You can detect weight with strain gauge and IR sensor together. Still, it sounds just hard. The weight variation is too large among people.

A store down the street has RFID tagged products and metal tube type detectors at the doors. They pick up the un-wiped (aka 5 finger discount) tags going through with no problem.

But I was thinking of active tags that could be read in any room. A tag count would be easy enough and if the same people always had the same tags you would know who as well as how many. You could easily enough detect if anyone was going around without a tag too.
