Hi all. I have been trying to find a schematic for a directional counter
for use in a door way. I have a circuit for a regular counter, however I
need to make it directional, counting just the people coming into the
room. I know I will need to use at least 2 infrared emitters, but I do
not know what to do from there. Any help would be greatly appreciated.
