Home Automation Systems (HAS) are becoming more and more common as a result of developments in communication technology. These systems are a part of Internet of Things (IoT) applications, allowing users to automate the remote operation of their home appliances. In this study, a low-cost Wi-Fi-based automation system for Smart Homes (SH) is proposed. This system enables remote monitoring and control of household appliances through an Android-based app. The fundamental component of the automation system is an Arduino Mega microcontroller with a Wi-Fi module. The system's flawless integration into the home network is made possible by this configuration. Multiple sensors are used to keep track of things like temperature, humidity, and motion in the home environment. To provide the best possible control and management of the household, these sensors provide useful data.A relay board is used to create a connection between the home's appliances and the home automation system. The connected appliances may now be operated precisely and under control thanks to this integration. The suggested automation system offers a simple and effective way to remotely operate electrical appliances inside the home by utilising Wi-Fi and the Virtuino mobile application. This study offers a viable and affordable method for integrating home automation systems into smart homes. Thanks to the Android-based application and Arduino Mega microcontroller at the heart of the system, homeowners can effortlessly monitor and operate their home appliances with simplicity through the integration of Wi-Fi technology and numerous sensors.
