Smart Switching System Using Bluetooth Technology

When being “SMART” is highly in trend nowadays, why stop only to smartphones or computers? So here the home appliances are made possible to control using a simple smart phone. An Android application is used to control the devices that are used in daily life. The other important devices that are used in this project are bluetooth module, microcontroller, relay board, and bulb. The hardware and software architecture of the whole system are described in this paper. It has been made sure that this venture can be accomplished under extreme low price so that it can easily be implemented in familiar atmosphere. This system was wirelessly controlled the switches from a distance of approximately 30 m radius. It is possibly used in health centre, nursing home, and home appliances for elderly, and Parkinson’s patients.
