CAMBRIDGE, UK — The IRS-B210ST01-R1 pyroelectric infrared (PIR) sensor is what manufacturer Murata claims to be the world's smallest at just 5.0×4.7×2.4mm, enabling the sensor to be used in compact, ...

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.

New thin film pyroelectric sensors, fast switching IR sources and suitable gas cell design enable new levels of ppm detection levels. Tighter legislation on environmental polutants and a public desire ...
