IoT Based Gas Leakage Detection and Prevention

This IoT-based Gas Leakage Detection and Prevention System is designed with ESP32, MQ-2 gas sensor, relay, buzzer, and 16x2 LCD display to ensure maximum safety. The MQ-2 continuously monitors gas levels. On detecting leakage, the buzzer provides an instant alarm, and the relay switches off connected electrical loads to avoid sparks or explosions. The LCD shows real-time gas status for immediate visibility.

This project is suitable for:

• Home safety automation
• Industrial gas leakage detection
• Final year engineering projects
• IoT and embedded system learning

With ESP32’s IoT capability, the system can be extended for mobile alerts, cloud logging, and remote monitoring. This ensures not only safety but also scalable future applications.
