ABSTRACT:
The project aims at designing an advanced home automation system using Wi-Fi technology. The
devices can be switched ON/OFF using a SMART PHONE through Wi-Fi.
Today is a world of advanced ubiquitous mobile applications which are used exhaustively to save time
and energy. These applications ease day-to-day life of a common man. Based on these technologies and
applications we designed a Home Automation System. In this paper, we propose design and prototype
implementation of home automation system that uses Wi-Fi technology and Android operating system.
An attractive market for Home Automation System is for busy families and individuals with physical
limitations. Users can control electrical appliances in home or office via smart phone.
DESCRIPTION:
Automation is the most frequently spelled term in the field of electronics. The hunger for automation
brought many revolutions in the existing technologies. These had greater importance than any other
technologies due to its user-friendly nature. These can be used as a replacement of the existing switches in
home which produces sparks and also results in fire accidents in few situations. Considering the
advantages of Wi-Fi an advanced automation system was developed to control the appliances in the
house. Wi-Fi (Short for Wireless Fidelity) is a wireless technology that uses radio frequency to transmit
data through the air. Wi-Fi has initial speeds of 1mbps to 2mbps. Wi-Fi transmits data in the frequency
band of 2.4 GHz. It implements the concept of frequency division multiplexing technology. Range of Wi-
Fi technology is 40-300 feet.

The controlling device for the automation in the project is a Microcontroller. The data sent from smart
phone over Wi-Fi will be received by Wi-Fi module connected to Microcontroller. Microcontroller reads
the data and decides the switching action of electrical devices connected to it through Relays and
switches. The Microcontroller is programmed used embedded ‘C’ language.
