Honeywell (HON) on Monday introduced a gas sensor that uses non-dispersive infrared technology to detect flammable gases including methane, propane and butane in industrial environments. The sensor is ...

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 ...

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.

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 ...

As drone threats push detection ranges outward, C-UAS performance is increasingly decided at the limits of visibility—where ...

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 ...

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 ...
