dc.description.abstractLiquefied Petroleum Gas (LPG) is widely used in Bangladeshi households, but its high flammability makes LPG leakage a critical safety concern. Very few detection systems exist, and the conventional ones are often expensive, grid-dependent and limited to alarms. This project presents a solar-powered smart gas leakage detection and management system for residential kitchens. The prototype integrates dual gas sensors (MQ-2, MQ-6), Arduino Uno controllers, GSM-based remote alert, Bluetooth-enabled subsystem communication, automatic ventilation through an exhaust fan and linear actuator and a solenoid valve to cut off gas supply. The batteries of the entire system are solar-charged and ensure continued operation with no human intervention. Testing under simulated leakage conditions confirmed accurate detection at a 2000 ppm threshold, rapid activation of safety measures, and stable performance for up to three hours on solar backup. Therefore, the system demonstrates a cost-effective, sustainable solution to improve household gas safety.en_US
