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 ...

Here’s a photo of my prototype: Because the design is based on the IR sensor module TSOP1838 from Vishay, it inherently supports the NEC format but can be easily extended to multiple IR data ...

That said, the Arduino is clearly the better option, as it offers boards capable of accommodating Arduino projects with ...

This specific sensor was chosen because others have successfully interfaced it with the Arduino. Not having to reinvent the wheel is good thing! For the build, [Brian] decided to hook up the IR ...

The sensor is really just an infrared photodiode inside of a tube. The diode is connected to an analog input pin on an Arduino. The sensor can be pointed at an object, and the Arduino can sense ...
