The world is full of automation and the people living in this world are surrounded with automated systems. Industries, business sectors, even homes are being automated. Operating various home appliances conveniently along with saving energy are the prominent factors possessed by Smart Home. A quick increase is seen in people's needs in order to develop the social economy of appliances present in a house. If we look at the existing system, we have Google home and Amazon echo which provide functionalities such as switching on/off appliances remotely from anywhere. This paper primarily focuses on a smart home system which allows users to control any electrical appliance using their smart phone google assistant. Apart from this the system also helps in keeping a track on air quality, sound and light intensity, temperature and humidity of home. It also provides analysis of the aforesaid parameters using various graphical methods. It starts the appliance itself on detecting human motion and notifies the user about the same so in case if there is an intrusion the user will come to know about the same. It also takes care of user’s safety as it informs about gas leakage and fire detection preventing any major damage. The need for integration is seen in society, as the idea of a Smart home system is still a new research area. Convenience, security, time management, and connectivity act as prominent factors to motivate and build a system like Smart Home. This paper hence provides a detailed inspection on the architecture, procedures, technologies required for a smart home system. The best protocols and technical solution acquired in the IOT Based Smart Home Assistant are discussed in the paper.
