Infrared (IR) Object Detection Circuit using IR Led and Photodiode

Infrared IR Object Detection schematic using  IR LED and Photodiode , IR Sensor Circuit

This project IR Sensor object detection module is quiet easy to make. This circuit here is a low cost / low range object detection IR Sensor module that you can easily make at home using IR sensors. We will use a photodiode and IR LED to make a simple circuit to make Infrared (IR) object detection module. IR led looks like a regular led that you usually see in Television Remote controls.
