Home Security System with RPi

Abstract

This project implements a real-time home monitoring and automation system using a Raspberry Pi integrated with multiple environmental and security sensors. The system utilizes a DHT11 sensor for temperature and humidity measurement, a PIR sensor for motion detection, an LDR for ambient light detection, an LM35 analog temperature sensor, and a smoke sensor for fire or gas leak detection. Data from these sensors are processed and uploaded to a remote server via HTTP using Python’s urllib module, allowing real-time environmental monitoring through a web interface. A relay module is also controlled remotely by reading a server status page, enabling or disabling appliances based on user commands. This system demonstrates an efficient and cost-effective solution for smart home automation, emphasizing IoT connectivity, real-time monitoring, and remote control.
