The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

He used a stepper motor to rotate the object being scanned, and an Arduino for control, but the real novelty is the way he used the sensor. [Fernando] mounted a Sharp GP2D120X on vertical surface ...

In the microcontroller era today, Arduino is more than just a tool to accomplish ... near 0.3s to 18s by the onboard potentiometer. Another sensor suitable for our project is the Infrared Proximity ...

We’ll demonstrate this sensor using a single resistor and a multimeter. Sharp GP2Y0D02 fixed 80cm IR proximity detector (Digikey #425-2064-ND, $14.38). Datasheet (PDF). The GP2Y0D02 requires a ...
