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 ...

(PhysOrg.com) -- Semiconductors provide the bases for many different avenues of device research. Indeed, many of the technological devices that are commonplace in our society are reliant on ...

Acoustic MXene plasmons detect weak molecular fingerprints in nanometer-thick films while extending infrared sensing into the short-wave infrared.

The presented schematic shows how to build a simple PIR motion sensor. PIR sensors allow motion sensing, it is almost always used to detect whether someone has moved in or out of the sensors range.

Raytheon has demonstrated a new type of infrared camera that ditches the conventional approach of capturing full video frames ...

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 ...

January 7, 2008 With each new sensor man invents, we find a way to a greater understanding of how physics plays out in the real world. Sometimes the value of the data revealed by a new sensor gives ...

Infrared sensors that detect the short-wave infrared (SWIR) region can clearly recognize objects not only during the day and ...

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body. All objects, living or not, ...

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 ...

WASHINGTON — An experimental U.S. Air Force missile warning sensor hosted aboard a commercial telecommunications satellite successfully observed the Oct. 28 launch of a NASA weather and climate ...

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 ...
