ABSTRACT
The main objective of this project is to develop a home automation system using an
Arduino board with Bluetooth being remotely controlled by any Android OS smart
phone. As technology is advancing so houses are also getting smarter. Modern houses are
gradually shifting from conventional switches to centralized control system, involving
remote controlled switches. Presently, conventional wall switches located in different
parts of the house makes it difficult for the user to go near them to operate. Even more it
becomes more difficult for the elderly or physically handicapped people to do so. Remote
controlled home automation system provides a most modern solution with smart phones.
A Bluetooth module is interfaced to the Arduino board at the
receiver end while on the transmitter end, a GUI application on the cell phone sends
ON/OFF commands to the receiver where loads are connected. By touching the specified
location on the GUI, the loads can be turned ON/OFF remotely through this technology.
The loads are operated by Arduino board through opto-isolators and thyristors using
triacs.
