Abstract: A home automation system using a Raspberry Pi enables users to control and monitor various devices within their homes remotely via the internet. This system typically involves integrating sensors, actuators, and a user interface (often web-based) with the Raspberry Pi, which acts as the central control unit. Users can manage lighting, appliances, and other systems from anywhere, enhancing convenience, comfort, and potentially energy efficiency. This paper proposes the design of Inter of Things (IoT) based home automation system using Raspberry pi. This project presents the design and implementation of an IoT-based home automation system using the Raspberry Pi as the central control unit. The system enables users to monitor and control household appliances such as lights, fans, and security systems remotely through a web or mobile interface, ensuring convenience, energy efficiency, and enhanced security. Using the Raspberry Pi's built-in Wi-Fi and GPIO capabilities, various sensors (e.g., temperature, motion, light) and actuators are integrated to create a smart environment. Communication protocols like MQTT or HTTP are employed to facilitate real-time data exchange between the devices and the user interface. The system supports both manual and automated control modes, making it adaptable to user preferences. This IoT-based solution offers a scalable, cost-effective, and user-friendly alternative to traditional automation systems, and it demonstrates the potential of Raspberry Pi in developing smart home technologies. User required to use different mobile devices like smart phones, Laptops, Tablets to operate the home appliances with the help of UI created on web page. Home automation plays an important role in establishing a smart home and is an ever exciting field that have grown largely over the last few years. New innovations has made the homes progressively appropriate, efficient and much increasingly secured. The low-cost devices used for joining the various electronic equipments and different sensors over an internet connection are supported and connected with the help of the Raspberry pi. Creating a smart home which can be effectively controlled and observed by the Raspberry pi by the means of Internet of Things is the principle target of present work.
