They work by having an emitter side that sends out a beam of human invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to IR, then the 'beam is broken' and the receiver will let you know. Compared to PIR sensors, breakbeams are faster
