I needed a multichannel line tracker sensor module for an upcoming project. A quick search found several versions of infrared line tracker sensor modules that met or exceeded my demands, but I picked ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

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.

Researchers at Northeastern University have developed a next generation smart sensor for the Defense Advanced Research Projects Agency (DARPA) that is capable of identifying infrared (IR) wavelengths ...

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 ...

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.
