Count people entering/leaving a shop?
-
My wife wants me to buy her a cheap IR based "Ding Dong Welcome" type door chime that makes a noise whenever someone enters her shop as she works a lot in the back office.
I'd prefer to pimp it out and make it sound a buzzer in the back office rather than startling the customer.... And why not count foot traffic while we're at it...
Has anyone seen a project like this before?

I used a cheap ebay infrared door minder in my parking sensor
it seems to work very well for the price.
