IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

The University of Hawaii (UH) has released the first image obtained using its new 16-megapixel HAWAII 4RG-15 (H4RG-15) image sensor on the UH 2.2-meter telescope on Mauna Kea. This represents a ...

To identify compounds or investigate sample composition, engineers often turn to infrared (IR) spectroscopy. Correlation tables can be found in various resources. One ...

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.

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 ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Oil and gas production and work in confined spaces exposes field personnel to a variety of toxic and explosive gases in everyday drilling, processing, transport, and municipal operations. Explosive ...

The Defense Advanced Research Projects Agency (DARPA) has announced a new program which seeks to enable quantum-level infrared (IR) detection at room temperature. The IR spectrum is a vast information ...
