Does it detect small children?
I'm guessing no, due to where he states he mounted the sensors.

I think the only issue I see for this is, in my house, it's a bit more OPEN, so I would only be able to implement this on upper floor rooms. My bottom floor has too much traffic in too open of a space. I'll have to rely on things like pressure pads on seats in order to tell if people are in the room.
Great idea! Great implementation! Would you be putting a kit together at some point? I'd love to put something like this in my upper floors. Especially the bathrooms!

Jon,
Bump?

Sorry, forgot to respond to this one
I think I can. I actually just ordered 3 PCB boards from ExpressPCB last night. I've never made a PCB board before, so hopefully it will go well. I can either give you the PCB board design file and component list, or have more printed and make a kit. The only hesitation I have is that I always tailor my devices to my house and individual design needs, so it might would require some modification for you to use it. For example, if you already have a RS485 network that you use, my network protocol I use for device addressing and commands is probably much different. Although you could probably get around that since the devices don't communicate to each other, just to the central computer. I'll put some thought into it and see what I can come up with.
how can you tell people is enetering or leaving a room? If you have a sensor can reliable tell that people are in it, you might not need any other sensor.It's a room counter by counting people entering. If you enter, it counts up. If you exit you count down.
If it goes up, you assume someone is in the room.

Jon, very impressive. I've been playing with occupancy detection/counting with commercial so-called "occupancy detectors" and, with much more success, a digital direction sensing infrared motion detector from Glolab (the DP-005) (used with counting logic) for almost a year now, but your solution offers a higher WAF for many of my doors and rooms.
Is all of the logic for detecting occupants done in the PIC and all of the counting logic done in the MisterHouse software or do you use the PIC for the counting too....?
