This project report presentation summarizes a home automation system developed using an Android mobile phone. The system allows remote control of home appliances like lights and fans using a Bluetooth-enabled Android phone as the central controller. The key components include an Android phone, microcontroller, Bluetooth module, relays, and household devices. The Android phone sends commands to the microcontroller via Bluetooth. The microcontroller then operates the relays to control the connected devices. This allows remote monitoring and control of home appliances through a mobile app for convenience. The system aims to provide a low-cost solution for smart home automation using widely available Android and Bluetooth technology.

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.  This has revolutionized the area of home automation with
respect to an increased level of affordability and
simplicity through the integration of home appliances
with smart phone and tablet connectivity.
 Smart phones are already feature-perfect and can be made
to communicate to any other devices in an ad hoc
network with a connectivity options like Bluetooth . With
the advent of mobile phones, Mobile applications
development has seen a major outbreak.
 Utilizing the opportunity of automating tasks for a smart
home, mobile phone commonly found in normal
household can be joined in a temporary network inside a
home with the electronic equipments.

4.  Home automation system is a mobile application developed
using Android targeting its vast market which will be
beneficial for the masses.
 According to the International Data Corporation (IDC)
Worldwide Quarterly Mobile Phone Tracker, Android
maintained its leadership position in global market share
Bluetooth is a short-range wireless communication
technology that comes in handy as the solution while
communicating over an ad hoc network environment like the
home environment for connecting the home appliances with
the mobile phones
 Bluetooth works over 2.4 GHz frequency range up to the
range of 100 m with 1 Mbps speed, providing a safe and
efficient solution for controlling home automation

5. REQUIRE COMPONENTS
1. ANDROID PHONE
2. MICROCONTROLLER (ATM89S52)
3. BLUETOOTH (HC-05 MODULE)
4. RELAY
5. RELAY IC (ULN2003)
6. TRANSFORMER (220V/12V)
7. VOLTAGE REGULATOR IC 7805
8. DIODE BRIDGE
9. LED’S AND BULB’S
10. RESISTOR,CAPICTOR AND CONNCETING WIRES
11. SUPPLY BOARD

6. 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.
 Android is everywhere. Present days Phones, Tablets, TVs and
set-top boxes powered by Google TV.
 Android was originally created by Andy Rubin as an operating
system for mobile phone twenty-first century. In 2005, Google
acquired Android Inc., and made Andy Rubin the Director of
Mobile Platforms for Google. Many think the acquisition was
largely in response to the emergence of the Apple iPhone around
that time.

7. Bluetooth Module:
 HC-05 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 voltage regulator.
 In the lowest power sleep mode
it merely consumes 500 nA and
will wake up within a few
hundred microseconds.

8. 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.

9. Interface :

10. Circuit diagram

11. Working :
 First bluetooth module connected to the android phone by
the bluetooth.
 Android phone alrady have a application to provide the
interfarence between mobile and the bluetooth module.
 By using the application ,the mobile send the command
signal to microcontroller by the bluetooth.
 Bluetooth and relay ic is connect to the microcontroller by
its pins.
 The relay is connected to the load by its pins.
 When microcontroller recives the command from mobile ,it
operate the load.

12.  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.

All loads OFF Load 1 is ON

15. 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.

16. 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.

17. 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.

18. 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.
