In recent years, the increased usage of Liquefied Petroleum Gas (LPG) in households and commercial kitchens has raised significant safety concerns, particularly in the event of gas leaks. This work presents the design and implementation of an Internet of Things (IoT) based smart kitchen safety system aimed at detecting LPG gas leaks, issuing real-time alerts, and initiating automatic safety measures, such as cutting off the gas supply. The system employs a gas sensor to monitor the concentration of LPG in the environment continuously. Upon detecting a leak beyond a predefined threshold, the system triggers an immediate alert through IoT-based communication. Simultaneously, a solenoid valve is actuated to disable the gas regulator, preventing further leakage and minimizing the risk of fire or explosion. The core of the system is powered by a microcontroller with Wi-Fi capability, enabling data transmission to the cloud. For remote monitoring and control, the Blynk IoT dashboard is used, providing a userfriendly interface that allows real-time visualization of gas levels, system status, and manual override of the gas valve if needed. Through Blynk, users receive instant alerts and can take prompt actions from their smartphones, enhancing the responsiveness and convenience of the system. This system not only ensures prompt response to hazardous conditions, is cost-effective, easy to install, and scalable, making it suitable for widespread adoption in both urban and rural settings.
