Researchers have developed a highly sensitive method for detecting hotspots in the environment, such as bushfires or military threats, by harnessing the focusing power of meta-optical systems.

We may receive a commission on purchases made from links. We've grown a little spoiled. At some point during the progression of televisions and media devices, remote controls went from infrared ...

Linux Infrared Remote Control (LIRC) allows you to use inexpensive hardware to control your Linux PC with a TV remote control. Why would you want to control your PC with a TV remote control? A number ...

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 ...

Thermal infrared (IR) energy is emitted from all things that have a temperature greater than absolute zero. Human eyes, primarily sensitive to shorter wavelength visible light, are unable to detect or ...

Michigan Technological University’s Michigan Tech Transportation Institute (MTTI) and Michigan Tech Research Institute (MTRI), in cooperation with the Center for Automotive Research and the Michigan ...

Non-dispersive infrared (NDIR) sensors are increasingly being used in multi-sensor instruments to measure LEL combustible gas. While they offer a number of significant advantages, NDIR sensors also ...
