There is a rapid increase in number of internet users. Smartphones have played a very important role in helping users with a much better internet service and different online applications. The concept of home automation is applied using internet of things. There was a time when people used to perform home automation using Bluetooth without using internet. Now technology has made a tremendous change and Bluetooth is switched to wifi. This paper presents the design, concept and implementation of IoT (Internet of things) based smart home automation with a low cost and better security. The system is easy and flexible as it uses Arduino board with various sensors to make the system effective. Password protection is used to allow only authorized users to use the system. The system works online as well as offline with the help of a smartphone and web. The system can control large number of devices or appliances at a time. Keywords— Arduino, IoT, Wifi, Web server. I. INTRODUCTION IoT refers to the networked connection of everyday objects, which are often equipped with more intelligence. IoT will increase the use of the Internet by integrating every device for interaction via embedded systems, which leads to a distributed network of devices communicating with objects as well as other devices. Thanks to rapid research in underlying technologies, IoT is opening lot of opportunities for a large number of applications that promise to improve the quality of our lives. Internet of things allows the sense of control across different objects with the help of a network infrastructure. Statistics show that IoT will consist of more 50 billion objects by 2020. Integration of internet to various different objects will have a unique IP addresses through which they will be connected. Embedded objects will have a low cost, low hardware and limited resources. IoT systems are not only responsible for sensing things but also for reacting to any command or performing actions. IoT systems are less complex with better space complexities and easy architecture. It plays an important role in providing secure ad flexible environment and it also maintains the living standard. Home automation system using IoT is a way through which one can explore and control home appliances or devices with the help of internet connection. IoT based home automation is a way of making home smart. Smart Homes can be described as technology within the home environment to provide convenience, comfort, security and energy efficiency. Using embedded system one can easily make a smart home and objects. Home automation can control each and every appliance or device with the internet. There was time when home automation was done with the help of Bluetooth and still it is existing with internet (wifi). In today’s world each and every one is using internet on mobile as well as computer. Internet has become the basic need for everyone and thus internet can be used for controlling the basic devices or appliances like TV, lights, fans, Air conditioners and much more.
