Ir Break Beam Circuit

Range of the circuit is about 5 meters if the transmitter and receiver are properly aligned.

Ir break beam circuit.

This circuit can do the job of a gatekeeper and intimates you if someone passes through the gate. Ir breakbeam sensor demo. 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. It is based on the working of the popular ir sensor module tsop1738 which senses 38 khz infrared pulses from the ir led of the transmitter.
