Smart Home System Using Android Application

A.J.C.E 01-Jan-15

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.

Due to the advancement of wireless technology, there

are several different of connections are introduced

such as GSM, WIFI, ZIGBEE, and Bluetooth.

What is Smart Home ?

Home automation system (HAS) involves introducing a

degree of computerized or automatic control to certain

electrical and electronics system in a building.

These lighting, temperature control, etc.., here 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.

SYSTEM OVERVIEW

The system is directly installed beside the

conventional electrical switches on the wall.

The target home appliances are controlled by the

system Main Control Board.

System provides three different types of physical

control methods to the Main Control Board.

The Bluetooth wireless connection enabled the system

communicates with graphical user interface (GUI) on

PC/laptop or smart phone without cable.

HARDWARE DESIGN

PIC Microcontroller, PIC18F2550 is chosen due to its

capability to perform the both serial and USB features

to establish the Bluetooth and USB connection to the

GUIs.

HSM-20G Sensor Module is chosen because it is the

low cost 2-in-1 combination of humidity and

temperature modules.

The Bluetooth module, low cost Cytron Bluebee

Bluetooth module is chosen to establish the Bluetooth

connection between main control board and the GUIs.

SOFTWARE DESIGN

Low Voltage Activating Switches

The switches detection function is

performed by the microcontroller, PIC.

The activating switches are designed

by push buttons. Any input switch is

pressed, it will interrupt the main

function loop of the PIC.

Then, the PIC will activate the relay

and toggle the current appliance’s

switch status.

SOFTWARE DESIGN

Window GUI

Window GUI is designed by an user-friendly interface.

The four bulbs indicated the appliances status that

connected to the system.

User can simply click on the bulb to turn on/off the

appliance.

Control board ‘Connect’ button is performed to establish

connection to main control board by Bluetooth or USB.

SOFTWARE DESIGN

Android GUI

. The application is designed in Android version 2.2

(Froyo) with API level 8.

The application is designed in low API level so that the

devices with higher version are compatible with it.

The interface is simple to use, user can simply touch on

the icon to turn on/off the appliances after connected to

the Window GUI or direct to the main control board.

The main advantage of “Home Automation through

Android Mobile” is that the “Physically Challenged

and Disabled People” .

Provide safety protection to the user, a low voltage

activating switches is replaced current electrical

switches.

The system is designed in user-friendly interface.

Low cost to design the system.

Ease of installation.

Advantages16

This low cost system is designed to improve the

standard living in home.

People can control their electrical devices via these

Home Automation devices and set up controlling

actions through Mobile.

Flexible types of connections are designed as backup

connections to the system.

In future this product may have high potential for

marketing.
