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.

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

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 ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

Substantial miniaturization of infrared (IR) sensors is necessary for their incorporation into next-generation portable electronics, wearable devices, and small satellites. However, modern infrared ...
