HOME AUTOMATION USING ANDROID PHONE OVER BLUETOOTH

Ab(t"!-t

The past decade has seen significant advancement in the field of consumer electronics.

Various ‘intelligent’ appliances such as cellular phones, air-conditioners, home

security devices, home theatres, etc. are set to realize the concept of a smart home.

They have given rise to a Personal Area Netor! in home environment, here all

these appliances can "e interconnected and monitored using a single controller.

#usy families and individuals ith physical limitation represent an attractive mar!et

for home automation and netor!ing. A ireless home netor! that does not incur

additional costs of iring ould "e desira"le. #luetooth technology, hich has

emerged in late $%%&s, is an ideal solution for this purpose.

'ome automation involves introducing a degree of computerized or automatic control

to

(ertain electrical and electronic systems in a "uilding. These include lighting,

temperature

(ontrol etc.

This pro)ect demonstrates a simple home automation system hich contains a remote

mo"ile host controller and several client modules *home appliances+. The client

modules communicate ith the host controller through a ireless device such as a

#luetooth ena"led mo"ile phone, in this case, an android "ased mart phone.
