This project demonstrates how to build an Intruder Alarm System using an HC-SR501 PIR sensor, Arduino Uno, a 5V relay, and a buzzer. The system detects motion using the PIR sensor and triggers the ...

Sensor used is a digital PIR sensor module; This is a basic circuit. It is possible to control Hi-Power sirens (pin D6), and flashers (pin D5) using suitable transistor/mosfet drivers; If you wish to ...

Hi there! I hope you are doing great. Today I am sharing the Proteus simulation of my project, in which I have shown the working of three sensors with a single Arduino. These include a PIR sensor ...
