A computerized home integrates technology to automate and oversee various aspects of the household, offering convenience, enhanced energy efficiency, security, and comfort. This setup includes smart devices, sensors, and systems that allow for remote control and scheduling. The system encompasses a variety of components, such as thermostats, lighting controls, security systems, and voice assistants, all of which collaborate to streamline tasks, reduce energy consumption, and bolster security. The process of home computerization results in the creation of intelligent living spaces that cater to a connected lifestyle. The proposed system is designed to computerize homes with an affordable and wireless infrastructure. Its primary focus lies in the development of an Internet of Things (IoT)-based home automation system, facilitating remote control of various components via the internet or automatic programming based on environmental conditions. By leveraging the NodeMCU IoT platform, a firmware is engineered to minimize the need for human intervention, ensuring the efficient operation of electrical devices. Different transmission modes enable seamless communication between the user, NodeMCU, and household appliances. The primary control system utilizes wireless technology, enabling remote access through smartphones via cloud server-based communication. A data transmission network enhances the automation capabilities of the system. With its user-friendly interface and straightforward installation process, this system effectively manages electrical appliances within a household. The proposed system empowers users to exercise internetbased control over any load through the use of an ESP32 Wi-Fi module, resulting in increased independence, safety, convenience, control, comfort, and energy savings.
