This composite structure diagram represents a home automation system, showcasing the key components and their interactions. At the core is a processor or microcontroller that connects and coordinates various elements of the system. These include click buttons for manual control, a graphical user interface (GUI) for monitoring and managing system operations, and a circuit board that integrates the components. Sensors collect environmental data, such as motion or temperature, while smart appliances like fans respond to user commands or sensor inputs. A network interface card enables communication with external networks for remote access. Together, these components create an integrated system for efficient and automated home management.
