I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

An IR repeater system takes Infrared (IR) light coming from your remote controller and converts it to an electrical signal that can be easily distributed over electrical wiring to one or more IR ...
