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.

From self-driving cars to facial recognition, infrared sensors are all around us and our novel semiconductor research is taking this technology to the next level. Phlux - a Sheffield spinout -has ...

STMicroelectronics is launching a human-presence and -motion detector to enhance security systems, home-automation equipment, and IoT devices that typically use passive infrared (PIR) sensing. The ...
