One reader asked how to use my arduino infrared library to detect breakage of an ir beam.
Ir break beam sensor.
2167 infrared ir break beam sensors are a simple way to detect motion.
When something passes between the two and its not transparent.
The answer was too long for the comments section so i ve extended into a blog post.
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.
How to build beam break detector for era shutter or flash ir short distance beam cut detector arduino ir breakbeam sensors adafruit learning system detecting an ir beam break with the arduino library a schematic of typical ndir sensor for gas detection b.
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.
I want to mount the detector 30cm away from the emitter.
When something passes between the two and its not transparent to ir then the beam is broken and the receiver will let.
