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 ...

Motion sensors can be built into individual luminaires or installed remotely to detect surrounding persons or objects. LED luminaires with inbuilt sensors are becoming increasingly popular and readily ...

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 major ...

Shortwave infrared light (SWIR) sensors are desirable in a broad range of applications, particularly in the service robotics, automotive, and consumer electronics sectors. Colloidal quantum dots tuned ...

Researchers developed a type of infrared photodiode that is 35% more responsive at 1.55 m, the key wavelength for telecommunications, compared to other germanium-based components. Detecting infrared ...

As the U.S. Army produces third-generation forward-looking infrared (FLIR) sensors, officials are exploring emerging capabilities that might be integrated into fourth-generation systems. FLIR ...

Most consumer remote controls operate using infrared light. This works well assuming the piece of equipment has a line of sight to the remote. But if you have, say a receiver in a cabinet or closet, ...
