Living objects with a body temperature above 0°C emit heat as infrared radiation, also known as thermal radiation, which is invisible to the human eye. PIR sensors, designed for this purpose, can ...

This project aims to create a circuit that can automatically switch a power source on and off based on the presence or absence of an object detected by an infrared sensor. The circuit features an ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Abstract: In this paper we propose a design for a home surveillance system with an enhancement circuit for the pyroelectric infrared sensor (PIR sensor) which has been included to improve the sensing ...
