interfacing the Chamberlain safety IR garage sensor model 801c with the BS2
im working on a school project where im attempting to build a IR counter for the school library to see how many people visit the library daily. unfortunetly, i cant find any datasheets on the chamberlain 801c online, and i can't prop the sensors cases open without destroying it. anyone have any idea on how i could possibly interface it with the basic stamp homework board so that i can use the sensor beams and a simple counting program to achieve my goal
