Smart homes are intelligent environments that interact dynamically and respond readily in an adaptive manner to the needs of the occupants and changes in the ambient conditions. Smart Home domain is a new trendy way of home automation and energy conservation. The realization of systems that support the smart homes concept requires integration of technologies from different fields. Among the challenges that the designers face is to make all the components of the system interact in a seamless, reliable and secure manner. Another major challenge is to design the smart home in a way that takes into account the way humans live and interact. “Internet of Things” is not a second Internet – it is a network of devices that are connected to the Internet that are used every day to search, upload images and connect with friends. It is a network of things that are connected to the Internet, thus they have their own IP address and can connect to each other to automate simple tasks. As a growing trend of urbanization, aging and individual-oriented lifestyle continues, the expectation for Smart Home is higher than ever. Smart phone apps that interact with one’s home will increase exponentially over the next few years.
In this project we propose a Cloud architecture which is based on digital appliances in smart home to provide IT Services that can be accessed and used by appliances users. As the nodemcu (12-e) that links Cloud and smart home, home gateway, which helps smart home merge into Cloud to provide more information services and access services provided by Cloud, plays a significant role in this architecture. Thus this Cloud architecture extends Cloud computing applications to a new domain so that more users could benefit from Clouds.An internet based home automation system focuses on controlling home electronic devices whether you are inside or outside your home. Smart Home gives an individual the ability to remotely or automatically control things around the home. Smart consist of rain water harvesting technique in which we store rain water and use it for house hold purpose so that the ground water is increase. Smart house Automation & security system using arduino, PIR sensor and camera with sms alert. Anything in your home that uses electricity can be put on the home network and at your command. Whether you give that command by voice, remote control or computer, the home reacts. A smart home or building is a home or building, usually a new one that is equipped with special structured wiring to enable occupants to remotely control or program an array of automated home electronic devices by entering a single command. For example, a homeowner on vacation can use a andriod phone to arm a home security system, control temperature gauges, switch appliances on or off, control lighting, program a home theater or entertainment system, and also built a smart geyser lights of stair case is get activated as per the motion of the person so that electric energy can be saved.
