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.

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 ...

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

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

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 ...

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 ...
