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 ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor. The main ...

The end result is that we now have projects like this ultra compact IR thermometer ... is that the LiDAR sensor was replaced with a MLX90614 IR temperature sensor. [gokux] has put together some ...

A new, higher-resolution infrared ... sensor development at NASA's Goddard Space Flight Center in Greenbelt, Maryland, as well as leading today's filter integration efforts. Jhabvala also led the ...

To do the same thing with your digital SLR you have to start by removing the IR filter over the sensor. If that sounds dangerous and hard to reverse, it is. So you might consider the Midnight Shot ...
