ABSTRACT

                         This project presents the development of
home appliances based on voice command using Android. This system has been
designed to assist and provide the support to elderly and disabled people at
home. Google application has been used as voice recognition and process the
voice input from the smart phone. In this project, the voice input has been
captured by the android and will be sent to the Arduino Uno. Bluetooth module
in Arduino Uno will receive the signal and process the input signal to control
the light and fan. The proposed system controls electrical appliances with
relatively user-friendly interface and ease of installation. We have
demonstrated up to 20 meter of range to control the home appliances via
Bluetooth.

 

I.INTRODUCTION  

The
home automation system (HAS) concept has existed in the emerging market and
becoming popular nowadays. Due to the advancement of wireless technology, there
are several different of connections was introduced such as global system for
mobile communications (GSM), WiFi, ZigBee and Bluetooth. Each of the system has
their own advantages and applications. Most of the systems used computer to control
the home appliances. Furthermore, this situation is not relevant nowadays
because the size of the computer is big and not easy to handle. As we know, PIC
programming is quite difficult because we need to design our own circuit. GSM
network system and internet has been implemented in HAS system The system using
radio frequency (RF) communication protocol has a lower cost compared to other
wireless communication methods such as Bluetooth. However Bluetooth has low
power wireless signals and used frequency hopping spread spectrum (FHSS) modulation.
This will help to avoid any interference from any other wireless devices and easy
to communicate with various Bluetooth devices. Here we uses the smart phone as
speech based remote control.

             

II.LITERATURE REVIEW

M.
B. Othman 1
presented the paper titled “Voice Control of Home Appliances using Android”.
This paper presents the brief idea about controlling of home automation by
using Bluetooth technology through smart phone and Ardunio Uno.

A.R.Al-Ali 2 and M.Al-Rousan
3 were the first
to develop Home automation system using java programming. It mainly used Wi-Fi
as a medium for communication between software and hardware component. The main
drawback was the range as the range of Wi-Fi was limited hence the user has to
be within the range. An android based home automation was then developed.  It used internet in the place of Wi-Fi and
its disadvantage was Unavailability of Internet.

B.Chakradhar 4 and S.Krishnaveni
5   presented the idea of
Bluetooth based Home automation. It used arm processor (ARM9 and ARM7), and so
the system has a complex architecture.

 R.Piyare 6 and M.Tazil 7 Department
of Electrical & Electronics Engineering Fiji National University has explored the ieee paper titled
“Bluetooth Based Home
Automation System Using Cell Phone”. This paper gives the detailed
information about how the and arduino and bluetooth  module interfacing in the automation process. 

 

III.EXISTING  SYSTEM

The existing system contains Wi-Fi
based using Arduino Microcontroller, Cloud Based Using Zig Bee Microcontroller,
GSM based using PIC microcontroller.

·       
The cost of
these systems are high

·       
These systems are complex in construction

·       
These systems
are not user friendly

 

IV.PROPOSED SYSTEM

Users can control the load by giving the input via the smart
phone either by using touch button or voice command. We used a different
character for identifying different function of the speed of fan and switch
ON/OFF the light. This project is very easy to
use in real life. People of any age can control it by just speaking the
commands.

                   Fig.2 Hardware
Connection Diagram

 

The Fig.2 shows the connection diagram of
voice controlled bluetooth module. A
single phase 230V AC supply is given to the 12V step-down transformer. A 12V AC
is given to the rectifier bridge and AC is converted into DC. Then 12V DC is
given to 5V regulator (LM 7805) and constant 5V is obtained. A 5V DC is given
to the arduino and from the arduino bluetooth module is connected. A 5V DC
output is given to the motor driver in order to control the speed of the fan
and the remaining are given to the relays to turn on and off the appliances.

VI.SEQUENCE OF OPERATION OF
APPLICATION

 

Step
1: The
application seek a permission from the user whether to enable the Bluetooth or
not.

Step
2:To configure
separate vocal command for the respective appliances

Step 3: This
shows that to choose which type of controller is to establish.

Step 4:
The Voice Controller receives the vocal commands and send that data to the
Bluetooth module which operates respective to the data received.

 

Figure 6 Reads according
to the data received

 

 

Step 4: The
Application disconnects the Bluetooth module .

VII.RESULT AND CONCLUSION

 

                In this system the command inputs are Speed1, Speed 2, Fan
off,Bright,Medium,Light off. To ensure this system successful ,each input must
have their own character. We troubleshoot each input button to make sure the
circuits are functioning well. From the evaluation, all the circuit are functioning
and working according to the programming that have been done in the Android and
Arduino. If “speed1” command is given the fan turns on and starts
rotating at maximum rpm and the character assigned for that is A. If  “speed 2” command is given the fan starts
to rotate in half of the maximum rpm and the character assigned for that is B.
If the “Fan off” command is given the fan turns off and the character
assigned for that is C. If “bright” command is given the LED starts
glowing at the maximum illumination level and the character assigned for that
is D. If “medium”  command is
given the LED starts glowing at the half of that maximum illumination and the
character assigned for that is E. If the “light off” command is given
the LED turns off and the character assigned for that is F.

 

CONCLUSION:

 

Voice
Controlled Home Automation is a very different concept than what is presently
available in the market. This would make automation easier. People will easily
interact with the system. It is also an important aspect in the present world
where people are so busy, this would help them in reducing the basic
functionality of their life. The world around us is going digital in every
aspect we can imagine and it is happening fast, we also need to move forward
with it. Our system is a great initiative step in automation, it would also
provide with security. As it is based on voice recognition we can assign particular
password to each user and the automation will respond to the correct passwords
only.
