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.

After decades of intense research, surprises in the realm of semiconductors—materials used in microchips to control ...

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 ...

InVisage's new image sensor for infrared cameras could help drones avoid trees and could aid virtual reality headsets in seeing where you're pointing. Stephen Shankland worked at CNET from 1998 to ...

Light sensors often use an infrared LED as a light source. Infrared LEDs have a greater intensity than LEDs that emit visible light. And when infrared photodiodes are used the sensors are relatively ...

The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

Trinamix partners with Aumovio to bring fingertip alcohol detection sensors to cars by 2029 using near-infrared spectroscopy ...

Traffic lights might seem like they let cars stop or go randomly, but that's not always the case. Many of them use special sensors that detect vehicles.
