The main objective of this project is to develop a home automation system using
an Arduino board with WIFI 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.
In order to achieve this, a WIFI 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.
