A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

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 ...

Our ability to learn more about insect behavior—which affects ecology, health, and economy on a global scale—depends largely on suitable recording technology. But until now, these tools have been ...

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 evidenced by the Covid-19 pandemic, quick and non-invasive techniques to assess body temperature have become necessary. In various locations, including hospitals, airports and schools, non-contact ...

Advanced-technology sensors, coupled with data processing and fusion and networked communications, have enabled new approaches to warfighting and have been essential for reducing combat losses, ...
