Design and development of smart branched switch for home automation systems

Our upcoming world needs a smarter way to control all the electrical and electronic appliances in one's home. The proposed concept in the paper will be very useful in achieving this. The control of the home appliances is achieved by the use of a single microcontroller, it has a branched structure with the microcontroller as the root memory and many RF transmitters as branches which will control many home appliance. The user interface is via an android application that runs on a smartphone that connects to microcontroller using WI-Fi where rooms can be added through application, as well as switches can be included to each room in the form of widgets thus displaying a live simulation of the network of switches in the home and shows whether they are active or inactive. The application ensures that the power is managed efficiently by indicating to the user, the connections that are turned on unnecessarily. This helps out in reducing the cost of and also saves energy.
