The Automatic Gas Leak Detection and Alarm System is a crucial safety device designed to detect and respond to gas leaks in a timely manner. By leveraging the MQ-2 gas sensor, Arduino UNO, and ...

🧠 Code Explanation The gas value is continuously read from the analog pin. If it crosses a threshold (default: 400), a buzzer sounds. The system is simple, but effective for demonstrating gas ...

This study offers an Arduino-based LPG gas leakage detection system with an automatic shut-off regulator to offset gas leak-related accidents. The proposed system uses an MQ-2 gas sensor to sense ...
