Gas Leakage Detection and Automatic Off System

The accidental leakage of gases like LPG poses serious risks in domestic and industrial environments. Thispaper presents an automated gas leakage detection and control system using an Arduino Uno and a servomotor. The system uses an MQ-2 gas sensor to monitor the environment. On detecting gas leakage, it notonly alerts users through a buzzer and LEDs but also physically closes the gas supply valve using a servomotor. The integration of low-cost components and an effective control mechanism makes this solutionboth reliable and affordable.
