Abstract


Liquefied Petroleum Gas (LPG) is commonly used for cooking in homes, but gas leakage and human error in handling the regulator can cause dangerous accidents such as fire and explosions. To improve safety, this project proposes an IoT-based LPG Regulator Monitoring and Control System. The system uses an ESP32 microcontroller with an MQ-6 gas sensor to detect LPG leakage and an IR flame sensor to identify fire. When a leak or flame is detected, a buzzer and LED provide an alert, and a servo motor automatically turns the regulator knob to the OFF position to stop the gas supply. The system is connected to the Blynk IoT platform, allowing users to monitor gas levels and receive notifications on their mobile devices. This solution offers a cost- effective and reliable way to enhance household safety and reduce risks related to LPG leakage.
