Globally accessible machine automation using Raspberry pi based on Internet of Things

In the present world, there are many high tech appliances in our homes that make our lives easier. It is necessary to control these appliances remotely. To automate a machine, a secondary brain (another machine) is required to `Think´ and control machines to do tasks as per the convenience of the user from long distances. An automation system is proposed for the users to control home electronic appliances with high mobility and security. A set of switches will be controlled by internet with the use of a Raspberry pi micro-controller board. A Raspberry pi micro-controller board obtains user input from a website that is accessed through a user name and password. The customized user friendly website has several buttons to control the appliances. A Raspberry pi will be located in a room and will be connected to all electronic appliances in the home with the help of electromagnetic relays. The Raspberry pi can be controlled from any distant place with the help of weaved cloud service. Webiopi framework gives us a platform to interact with Raspberry pi´s General Purpose Input Output pins. The Raspberry pi then either passes or stops current through an electromagnetic relay connected to the intended switch and this closes/opens the circuit allowing the appliance to run or get switched off. Thus globally accessible automation of electronic appliances can be made possible with the use of a Raspberry Pi micro-controller board, an internet connection and relay switches in a user friendly way.
