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 ...

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

The second paper, appearing in the journal Nano Letters and led by graduate student Pooja Reddy, describes a clever method to ...

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 ...

Fractals are becoming popular for when it comes to designing microwave and radio-frequency antennas thanks to their “self-similarity” that allows the antenna to better collect and focus broadband, ...

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 power switch with infrared proximity sensor is intended for the recognition of obstructions at distances of a few millimetres to a few centimetres. This compact sensor switch can be used to open a ...

Under the JST Strategic Basic Research Program PRESTO, Associate Professor Ayumi Ishii of Teikyo University of Science with her team members has developed a new near-infrared light sensor by using a ...

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.

It is critically important for instrument users to understand what the sensors in their instrument cannot properly measure, as well as what they can. Non-dispersive infrared (NDIR) sensors are ...
