E18-D80NK Infrared Proximity Switch
Arduino infrared proximity switch module is a reflection-type photoelectric sensor which integrates transmitting and receiving infrared beams. Infrared proximity switches work by sending out beams of invisible infrared light. A photodetector on the proximity switch detects any reflections of this light. These reflections allow infrared proximity switches to determine whether or not there is an object nearby.

The table below showcases the pin configuration of the IR proximity sensor. It has 3 output wires, which are generally colour-coded with Red as VCC, Green as the ground, and Yellow being the Digital output.
|Pin Type/Wire color||Pin Description|
|Digital pin(Yellow)||Digital signal output|
Note: The general colour coding of the wire may vary in the E18-D80NK IR sensor from different manufacturers or distributors. Kindly follow the suitable datasheet for connections.
Some other common color code is: Brown: VCC, Black: Output, Blue: Ground
