2. What is Home Automation?
 Home automation involves introducing a degree of
computerized or automatic control to certain
electrical and electronics system in a building.
 These lighting, temperature control, etc.., this paper
demonstrate a simple home automation system
which contains a remote mobile host controller and
several client module (home appliances).
 The client modules communicate with host
controllers through a wireless device such as a
Bluetooth enabled mobile phone, in this case, an
android based smart phone.

3. ANDROID
 Android has an active community of developers
and enthusiasts who use the Android Open
Source Project (AOSP) source code to develop
and distribute their own modified versions of the
operating system.

6. INTRODUCTION
 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 paper presents a possible solution whereby the
user controls devices by employing a central Field
Programmable Gate Array (FPGA), where control
is communicated to the FPGA from a mobile phone
through its Bluetooth interface.

7. COMPONETNS USED
The Main components used in
HAAM is
1) Bluetooth module
2) Relay

8. Bluetooth Module:
 BLE112 is a Bluetooth Smart
module targeted for low-power
sensors and accessories.
 It integrates all features
required for a Bluetooth Smart
application.
 It is powered directly from a
standard 3V coin cell battery
or a pair of AAA batteries.
 In the lowest power sleep
mode it merely consumes 500
nA and will wake up within a
few hundred microseconds.

9. Relay :
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. Interface :

12. Working :
 It uses M-8870 DTMF (Dual Tone Multi
Frequency) decoder IC which decodes tone
generated by the keypad of cell phone.
 Data is transmitted as pairs of tones.
 DTMF signal can be tapped directly from the
microphone pin of cell phone device.

14.  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.

15. Screen Shots :

16. The system should be scalable, so that new device can
easily be integrated into it.

17. Control of electrical appliances through an
application of Automation in our Android Mobile

18. SOFTWARE DESIGN:
Android uses Bionic in place of a standard C library,
originally developed by Google specifically for
Android, as a derivation of theBSD's standard C
library code.
Bionic has several major features specific to the Linux
kernel, and its development continues independently
of other Android's source code bases.
The main benefits of using Bionic instead of the GNU
C Library (glibc) oruClibc are its different licensing
model, smaller runtime footprint, and optimization for
low-frequency CPUs.

19. Applications :
 Yet 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 wireless technology is especially useful in home
environment, where there exists hardly any
infrastructure to interconnect intelligent appliances.

20. Advantages :
 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.

21. Conclusion :
 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.
