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.

This system can monitor when a sheet of glass has either water or ice on its surface, and then generate a PWM signal to control a motor that wipes away the liquid from the glass surface. In this ...

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...
