Home Automation System (HAS) is becoming increasingly popular with the advancement of communication technology. A smart home is a better implementation of the Internet of Things (IoT), offering users the convenience of controlling home appliances on the Internet through an automated system. This paper presents a low-cost smart home automation system using Wi-Fi to support remote control and monitoring of home appliances via an Android application. The system is constructed on the basis of an Arduino UNO microcontroller equipped with a Wi-Fi module. In addition, several sensors are implemented to sense temperature, humidity, and motion inside the residence. A new system overcomes the limitations of the existing home automation systems. This is achieved by design and construction a low cost Wi-Fi-based Automation System for Smart Home prototype using Arduino microcontroller and Android-Based smartphone. An automation system is interfaced with home appliances with the help of a relay board. The proposed architecture facilitates optimal and easy control of electrical and electronic appliances with the help of Wi-Fi and a virtual mobile interface.
