Description

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.
