E18-D80NK Infrared Obstacle Avoidance Sensor contains an infrared transmitter and receiver which together make up a photoelectric sensor. The sensor has a long detection distance, and has less interference by visible light because it uses modulated Infrared light. This sensor has a screwdriver adjustment to set the detected distance, then gives a digital output when it senses something within that range. This sensor does not return a distance VALUE. It has 3 connecting wires:
Red: +5 VDC
Black: Ground
Yellow: Output-Open collector pulldown( Use 10K pullup resistor to +5V)
It is widely used in robot obstacle avoidance, and many other automation products. The technology behind this effective distance sensor is modulation of infrared light. The receiver is sensitive only to infrared light. Therefore it is not very sensitive to ambient light compared to plain infrared detectors.
