Chris at The Keeser has constructed a simple circuit to detect infrared light. You can make the project using only 7 parts. A schematic and analysis of operation is also provided. Parts Needed: “Test the circuit by holding it close to an IR remote control and pressing any button. If everything is working (including the remote control) then the LED should light up.” |

I like the simple circuit. Just to let people know that most video cameras can also be used to detect IR light, it just glows like a normal led in the viewfinder!

Nice small size. This would be great in a repair shop to test remote controls.
