It is meant to save the electric power and human energy . In modern times, people prefer more of automatic systems rather than manual systems. One of the latest, emerging and trending technologies is the ǮInternet of Thingsǯ. Here electric appliances are operated by the website. The main objective of home automation and security is to help handicapped and aged people that will enable them to control home appliances and alert them in critical situations. Home Automation System uses the technology of Internet of Things for monitoring and controlling of the electrical and electronic appliances at home from any remote location by simply using a Smartphone. Cloud based platforms help to connect to the things around us so that we can access anything at any time and any place in a user friendly manner using customized portals and in built applications. Hence, cloud acts as a front end to access IOT. Key Words: Cloud Computing, Internet of Things (IOT), Home Automation, Raspberry Pi, Wi-Fi. INTRODUCTION Wi-Fi E Switch is a web based system using Raspberry pi. As it has lot of GPIO ports which can be programmed and they provides user control over various things from smartphone like energy saving, security, smart system, surveillance, access control and entertainment [1]. The main aim to design a system is to save time and manpower along with maintaining convenience and security. This system is simply design to provide comfort, security and it is easily accessible. Internet based Home Automation System is very convenient, easy flexible and cheap [2]. Many devices now have Wi-Fi and can connect to Smartphones or home computers. But these devices cannot communicate with each other or else need additional devices to do so. Thus, these devices need to be unified, such that they can be monitored and controlled using one single program or device, e.g. controlling lights, fans, air-conditioners, oven, refrigerator, TV etc. by using an application on the Smartphone [3]. Fig. 1 Internet of Things Wireless systems can be of great help for automation systems . With the advancement of wireless technologies such as Wi-Fi, cloud networks in the recent past, wireless systems are used every day and everywhere. IOT coverage is very wide and includes variety of objects like smart phones, tablets, digital cameras and sensors [3]. Once all these devices are connected to each other, they enable more and more smart processes and services that support our basic needs, economies, environment, health etc. Such enormous number of devices connected to internet provides many kinds of services and produce huge amount of data and information. This is very easy to install and require very less energy i.e. 0.6mV. PROBLEM DEFINITION The system offers switching functionalities to control the appliances connected to the system, which includes Lights, Fans, Air-conditioners and various other appliances connected to the system. In India, the alternating current supplied to our homes is of 230V. Arduino Board is not capable of withstanding such high Voltages. Thus, Relays are used to convert this high voltage to low voltage i.e. less than 5V. The relay switches have capability to carry a maximum load of 10A at 240V. To enable connectivity with the microcontroller Wi-Fi module is used. It provides Internet connectivity, which allows Internet access and control from the Android Application effectively and efficiently.
