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 ...

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [… ...

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

For the infrared remote control, [Meseta] dug into Lady Ada’s IR sensor tutorial and decoded buttons 1 through 4 on a Sky TV remote.

Passive infrared (PIR) sensors detect infrared energy radiating from objects within their field of vision.

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be ...

Researchers have developed a smart sensor for DARPA that’s capable of identifying infrared -- without having to have its own power source.
