Proximity Sensor/Switch
E18-D80NK
Description
A very cheap, easy to assemble, easy to use Infrared sensor with a long
detection distance and has less interference by visible light. The implementations
of modulated IR signal immune the sensor to the interferences caused by the
normal light of a light bulb or the sun light. This sensor has a screwdriver
adjustment to set the appropriate detected distance to make it useful in many
applications, and then gives a digital output when it senses something within that

collision avoidance robot and machine automation. The sensor provides a non-
contact detection.

Testing
1. Please check all the connections from the given wiring diagram.
2. Type the sample program in your Arduino sketch then upload.
3. Open the serial monitor in the upper right corner.
4. When there is no object in front of the proximity sensor, the output must be 1.

5. Try to put an object in front of the proximity sensor, the proximity sensor will
light and the output will become 0.
Note:
* If there is no change in the output of proximity sensor, try to move the
object closer.
* Adjust the screw in the proximity sensor to change the range of detection.
