An Affordable and Effective IoT-Based Home Automation and Security System for Everyone

Modern homes are rapidly transitioning away from manual switches to centralized control systems that incorporate remote-controlled switches. As we enter the age of artificial intelligence and ubiquitous computing, home security and management have become a critical issue to address. In this project an inexpensive, IoT-based home automation and security system is developed that can be used to control various switches inside the home and to protect the house during the absence of owners from the premises. The proposed system utilizes an Arduino board, Node MCUESP8266MOD micro-controller and security system incorporating RFID, motion detection, flame and gas alarms. An android mobile application with voice command feature is developed to control the system. The proposed system is then tested to perform optimally with the average operating delay found to be less than that of similar devices that are currently available in the market. In a cost analysis comparison with competing devices, our proposed system at only USD 31 costs significantly less in terms of module and sensor prices.
