In today's world, Automatic systems are being most popular over manual system. With the fast increase within the variety of users of web over the past decade has created web vicinity and parcel of life, and IoT is that the latest and rising web technology. Web of things could be a growing network of an everyday object-from industrial machine to trade goods that may share info and complete tasks whereas you're busy with different activities. Wireless Home Automation system (WHAS) mistreatment IoT could be a system that uses mobile devices to manage basic home functions and options mechanically through Wi-Fi network, an automatic house is typically referred to as a sensible home. It is meant to avoid wasting electrical power and human energy. During this project, we tend to gift a Home Automation System (HAS) mistreatment NodeMCU that employs the management of varied lights, fans, and appliances at intervals in their home. This method is intended to be low priced and expandable permitting a range of devices to be controlled. Keywords— Internet of Things (IoT), Home Automation System (HAS), NodeMCU, Google Assistant (GA) I. INTRODUCTION Today, technology trend has become an associate degree integrated a vicinity of people's lives. It has, and continues to influence of many aspects of a way of life and has allowed higher social interaction, easy transportation, the power to fancy diversion and media and has helped within the development of drugs. The creation of the many devices like mobile phones and computers has caused many of us to have faith in technology to speak with their friends, store info like footage, movies, documents, and music. The net has become a standard interface that several devices use to change the way of life of the many folks. The net has given folks the power to go looking for info, store their info within the cloud whereas conjointly giving them higher ways in which of managing info. From the time of its introduction, the quantity of individuals that use mobile phones and also the net to speak with others has increased dramatically to become one amongst the most important means that of communication. Smartphones have allowed folks to attach to the net while not the requirement for a laptop, whereas still giving similar practicality however through totally different means that. With the introduction of higher hardware and the next code, Smartphone has become one among the powerful devices and have become an important a part of people's daily lives. A significant reality is, however, the Smartphone is prepared to connect and communicate with various devices. For example, Smartphones
