Smart Home or Office Automation through Android mobile

Now a day’s so many useful technologies are coming out to make our lifestyle more comfort, luxurious and secure.
Especially in mobile field so many applications are being developed to give us more information and entertainment.This project is designed with a combination of two latest and most demanding technologies that are Android and Embedded Systems
Android is a Linux based operating system designed primarily for mobile devices and it is an open source. There are so many applications are already developed on Android and many applications are being developed at free of cost for its users.
We can also develop our own customized applications with free of cost or with minimum cost according to our requirements.
In this project we will create an application to control electrical appliances like fan, lights and water pump motors in home or office. Whenever we operate this application, it sends commands to our controlling system through blue tooth.
At controlling system side, we have Bluetooth module, micro controller and load controlling circuits. Whenever this blue tooth module receives commands from android application, then it transfers this command to the micro controller. Micro controller will control the respective loads depends upon the command it received
This is very safe and secure and also we can control many loads without getting confused by adding names or images in the application.
