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.
Technical Specifications:

Pinout:
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 |
| VCC(Red) | Voltage input(+5V) |
| GND(Green) | Ground terminal |
| 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
