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 ...

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. The key ...

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

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 ...

We all know that feeling: you've turned the lights off and are almost asleep when you hear that infamous buzz. A mosquito is hunting in your bedroom. The dance commences. You could turn on the lights, ...

A technology that enables the fabrication of "ultra-miniature infrared sensors" in desired shapes and sizes using room-temperature three-dimensional (3D) printing has been developed for the first time ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

New room-temp 3D printing makes microscale infrared sensors customizable and energy-efficient, reducing production costs and expanding design options. (Nanowerk News) A new 3D printing method could ...

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 ...
