Cost Effective IoT Based Smart Home Automation System: Design, Implementation, and Security Features

The increasing adoption of Internet of Things (IoT) technologies has paved the way for smart home automation systems that provide efficient and user-friendly solutions for controlling household appliances and gadgets. This study proposes a cost-effective IoT-based smart home automation system designed to address affordability and ease of use for small businesses and regular users. The system enables seamless control of appliances through voice commands, physical activity sensors, and a mobile application interface. The proposed system connects home devices and appliances via Wi-Fi and utilizes a central processing unit to manage Internet of Things (IoT) operations. It features a software development kit (SDK) that simplifies the connection, configuration, and control of both new and existing appliances. The SDK also supports third-party device integration, providing flexibility for future expansions. To enhance security and reliability, the system employs 256-bit Advanced Encryption Standard (AES) encryption for end-to-end communication between the central control hub, device controllers, and the cloud. Automated device inactivity detection and power shutdown capabilities are integrated to optimize energy efficiency. The mobile application allows users to customize scripts for automated tasks and supports real-time monitoring of appliance performance. This smart home automation system combines affordability, simplicity, and robust security measures, making it a versatile solution for domestic and commercial eco-systems. The platform's scalability and customizable features highlight its potential to revolutionize modern living environments while addressing user demands for seamless control and energy efficiency.
