2. INTRODUCTION
 Home automation is anything that enables you to
use your home's lighting, heating and appliances
more conveniently and efficiently.
 Common tasks include turning off lights when no
one is in the room, locking doors via smart phone.

3. WHAT IS HOME AUTOMATION?
 Home automation involves introducing a degree
of computerized or automatic control to certain
electrical and electronics system in a building.
 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.

4. 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.

5. COMPONETNS USED
 1) Bluetooth module
 2) Relay

6. BLUETOOTH MODULE,
RELAY
Bluetooth module Relay
BLE112 is a Bluetooth Smart
module targeted for low-power
sensors and accessories.
A relay is an electrically
operated switch.
In the lowest power sleep mode
it merely consumes 500 nA and
will wake up within a few
hundred microseconds.
Relays are used where it is
necessary to control a circuit by a
low-power signal.
It is powered directly from a
standard 3V coin cell battery or a
pair of AAA batteries.
Relays protect electrical
circuits from overload or faults.
It integrates all features
required for a Bluetooth Smart
application.

7. 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.
 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.

9. 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.

10. 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.

11. CONCLUSION :
 In future this product may have high potential
for marketing.
