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 ...

This repository demonstrates how to implement motion detection using a PIR sensor with an LED and serial output across multiple platforms like Arduino Uno, ESP32, Raspberry Pi Pico, and STM32 Nucleo.

This project implements a secure password-based unlocking system using an Arduino Nano, featuring motion detection via a PIR sensor, password input through a 4x4 matrix keypad, and user feedback via a ...

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 ...

In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present challenges such ...
