Gas leakage and poor management of kitchen safety and leakage of gases continue to be major causes of domestic accidents, damages to property, and severe health risks. Due to the fast performance of Internet of Things (IoT) technologies, nowadays, it is possible to implement measures against such risks in the form of intelligent monitoring and automated safety measures. The current paper outlines the design and implementation of a gas safety alert and smart kitchen monitoring system based on IoT technology that has a mobile application as a remote monitoring and control tool. The suggested system will constantly check the important environmental parameters including gas level, temperature, and the weight of the LPG cylinders with the assistance of sensor data which will be delivered via the Blynk cloud platform. An Android mobile app created on Android Studio is a secure user interface that has authentication capabilities and allows users to see real-time sensor readings and remotely control kitchen appliances. In case of any degrading situations like gas leakage, extreme temperature, etc. The system will automatically start various safety systems like the instantaneous mobile notification, audible alert systems, automatic shut-off of the stove and activating the exhaust fan to avoid the possibility of gas build-up. Moreover, the system gives in to predictive cylinder monitoring as it constantly monitors the cylinder weight of LPG so that the user gets informed whether the gas is low and if he or she needs to replace it. Virtual data streams and dashboards on clouds will keep the data synchronized in real-time between sensors, simulation modules, and the mobile application. The modeling system of sensor behavior and emergency situations with the help of a Python based simulation environment proves that the system can identify unsafe situations and take timely security measures. The given solution should provide customers with a fast, economical, and easyto-use structure of smart home gas security that could increase the level of protection of households by eliminating accidents before they happen.
