The necessity for safety and security-based systems has grown tremendously in our daily lives, and their significance has also increased notably. These systems are now essential for safeguarding people's homes, workplaces, valuable assets like gold stores, and countless other institutions. However, defense against the possibility of catastrophic incidents such as gas leaks, fire outbreaks, or burglary attempts emphasizes the significance of the same. The development of intelligent electronics and smart microcontrollers has led to a notable surge in technological advancements in recent times. This paper outlines the design of a security system used in managing a multi-level home using the versatile Atmega328 microcontroller board. This management system is designed to operate seamlessly accepting both remote and local control. The results achieved from the proposed system commendably display an admirable level of performance reliability, hence making it suffice for integration within Internet of Things (IoT) applications. This system stands out due to its ability to function independently of various points of failure, which makes it more dynamic and able to hold sustained service. The suggested system's affordability makes it a viable application for a cross-operation of upstream, midstream, and downstream settings, enhancing security and strengthening defenses against floods in different forms that could compromise the security architecture. Hence, the research described in this paper not only portrays a solution with strong security and safety aspects, but also establishes doors for its practical implementation across various circumstances.
