Abstract: Gas leakage poses a significant threat in residential and industrial environments, often leading to hazardous situations like fires and explosions. This paper presents a Smart IoT-based Gas Leakage Detection and Auto Shut-off System that enhances safety by integrating real-time monitoring with an automated response mechanism. The system detects gas leaks using an MQ-6 sensor and promptly shuts off the gas supply through a servo motor-based valve control. Additionally, an alert notification is sent to users via an LCD display and buzzer to ensure immediate awareness. This paper discusses the half implemented version of the system, focusing on gas detection and auto shut-off functionalities. The proposed system improves upon existing gas detection techniques by offering a cost-effective, highly responsive, and automated approach to preventing gas-related accidents.
