IoT-Driven Environmental Safety Monitoring Platform with Predictive Hazard Detection and Smart Control

The IoT-Driven Environmental Safety Monitoring Platform with Predictive Hazard Detection and Smart Control is an advanced embedded system designed to enhance safety in residential, commercial, and industrial environments. The platform integrates multiple sensors, including an MQ2 gas sensor for smoke and combustible gas detection, a flame sensor for fire identification, and a DHT11 sensor for temperature and humidity monitoring.

Powered by an ESP32 microcontroller, the system continuously analyzes environmental conditions and identifies potential hazards before they escalate into critical emergencies. Through predictive monitoring algorithms, the platform can detect abnormal gas concentrations, fire presence, and rising temperatures, enabling proactive safety measures.

Upon hazard detection, the system automatically activates a buzzer alarm, controls a DC exhaust fan through a relay module for ventilation, and displays real-time safety information on an OLED display. IoT connectivity allows remote monitoring, event logging, and instant notifications, ensuring users remain informed regardless of location.

The power supply section utilizes a 12V transformer, bridge rectifier, filter capacitor, and 7805 voltage regulator to provide stable and reliable operation for all system components.
