Abstract: Liquefied Petroleum Gas (LPG) is extensively used in residential buildings, hotels, restaurants, or other cooking places due to its convenience and efficiency. However, gas leakage might occur from the cylinder, regulator, or connected pipes accidentally, which causes fire accidents, explosions, and even property damage. The situation becomes dangerous when the leakage is not detected on time or nobody was present to manually turn OFF the regulator. Common practices of gas leakage detection systems generally detect gas sensor presence and raise an alarm but do not physically shut OFF the gas regulator. This project aims to propose a Smart Gas Leakage Auto-Shutoff Electrical Clip, which detects LPG leakage automatically and operates an external clip to move the regulator to the OFF position. The project implements an MQ-6 gas sensor and Arduino UNO microcontroller to control a high-torque MG996R servo motor, which rotates the specially adapted retrofit clip to demonstrate the auto-shutoff mechanism. A similar buzzer circuit is designed for emergency alert purposes. In contrast to the common practice of the IoT-based remote-controlled gas leakage detection system, the proposed concept concentrates on direct detection and automated external clip operation, which physically moves the regulator to the OFF position via an embedded system. The electrical clip can be placed externally to the current regulator and does not require a complete redesign of the existing structure. The compatibility can be achieved conditionally depending on the shape and size of the existing regulator. The proposed concept can be further validated by testing the sensor, clip mechanism, and servo motor, followed by multiple repetitive tests for desired result accuracy. The project aims to propose a cost-effective and reliable concept for the improved safety of LPG and reduced human intervention. However, additional mechanical and safety tests need to be done for the concept to be applicable to the actual LPG cylinder
