Although it s invisible to the human eye infrared ir light is very useful in electronics.
The ir infrared light barrier kit contains an ir emitting module and an ir receiver module with an led indicator and buzzer.
By combining these two cell types active infrared barriers form an immaterial wall.
As long as the receiver is detecting the ir light from the emitter it will remain silent.
This is an electronic kit and requires assembly.
Receiver cells that detect the beams and analyze wheather they are correctly received.
Maximum range is approximately 13 feet.
The transmitter emits a beam of infrared light which is invisible to the human eye.
The transmitter sends an infrared signal to the receiver when the signal beam is broken it will sound a buzzer.

It is not for a safety device.
Used to enhance capabilities of many electronics projects because of their low cost and wide availability ir devices create invisible barriers which trigger a circuit when the light beam is broken.
Basically it would be a series of ir led s mounted 1 2 apart on a bar total height.
