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 ...

Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

These types of thermometers use infrared sensors to measure infrared radiation from a hot body to accurately calculate the temperature. So, in this project, we will explain how we can make such a ...
