3. There is an increasing demand for smart
homes, where appliances react
automatically to changing environmental
conditions and can be easily controlled
through one common device.
This project presents a possible solution
whereby the user controls devices by using
their existing mobile phone ,where control is
communicated to the Microcontroller from
a mobile phone through its Bluetooth
interface.

6. HC-05 is a Bluetooth Smart
module targeted for low-
power sensors and
accessories.
It integrates all features
required for
a Bluetooth Smart
application.

In the lowest power sleep
mode it merely consumes 500
nA and will wake up within a
few hundred microseconds.

7. It is preferable to use Bluetooth because now a days people have
their smart phones with them all the time, since the smart phones
have Bluetooth facility in them, thus it's better to use Bluetooth
rather than using RF remotes or IR remotes. Have you ever seen
people carrying remotes???

8. A relay is an electrically
operated switch.
Relays are used where it is
necessary to control a
circuit by a low-power
signal.
Relays protect electrical
circuits from overload or
faults.

10. First Bluetooth module connected to the android phone
by the Bluetooth.
Android phone already have a application to provide the
interference between mobile and the Bluetooth module.
By using the application ,the mobile send the command
signal tomicrocontrollerby the Bluetooth.
Bluetooth and relay ICis connect to the
microcontroller by its pins.
The relay is connected to the loadby its pins.
When microcontroller receives the command from
mobile ,it operate the load.

11. This wireless technology is especially useful in
home environment, where there exists hardly any
infrastructure to interconnect intelligent appliances.
It could be suitably used for home automation in a
cost-effective manner. Operating over unlicensed,
universally available frequency of 2.4 GHz, it can
link digital devices within a range of 10 m
(expandable to 100 m, by increasing the
transmitted power) at the speed of 1 Mbps.
Building upon this theme; we propose a home
automation system based on Bluetooth
technology.
The overall system should be fast enough to realize
the true power of wireless technology.

14. The main advantage of “Home Automation
through Android Mobile” is that the “Physically
Challenged and Disabled People” .
Replace television, air conditioner etc., remotes for
sleep mode.
Smart Home.

15. Home Automation is undeniably a resource
which can make a home environment
automated. People can control their electrical
devices via these Home Automation devices and
set up controlling actions through Mobile.
In future this product may have high potential
for marketing.
