Abstract—Entry of new trend brings many new
appliances. One of the new applications is wireless home
automation using smart phone. Here we are to interface
the A/C devices like BULB,FAN, etc with the smart phone.
We need to design an android application which would be
interfaced with the GSM device placed on the kit.
According to the button pressed on the app a coded
message will be generated. The coded message will vary
according to the button pressed. So the coded message will
be transmitted to the kit with air as the medium, i.e., GSM.
The transmitted message will be received by the other
GSM modem placed at the device board. According to the
message received, controller is going to control the devices.
One of the most advantageous matters is that from any
place in the world we can communicate with the device.
Key words: - GSM, coded message, device kit.
I. INTRODUCTION
Till today we have seen many home appliances controlled
with help of some solid medium. Our TV’s, bulbs, fans, A/C’s
etc are working on the switch, which has a connection from
the switch to device. So whenever the individual want to
switch ON the device he has to get up from the position and
switch ON the respective button and whenever he want to
switch OFF that device he has to again need to get up from the
position and switch OFF those respective device. Let us
consider if the individual has forgot to switch OFF the devices
and left for office or on any other work then devices would be
in the ON mode till he/she returns back and feel sorry for the
power wastage. By this there would be not only the wastage of
power but also there would be wastage of money. When
coming to the matter of power utilization factor, this would be
the serious problem in developing countries like India.So to
avoid all such wastages and to increase in the utilization of
power our proposed system helps to do it. But our proposed
system mainly uses air as the medium to transmit the
information. So we are using GSM as the wireless device to
transmit information.
II.PRINCIPLE AND WORKING
using any hardware circuit. The received data would be in the
forms of bits and the receiver would be combining those bits
and performs its assigned task. The data stored in the app
would be something like “TURN ON LIGHT”, when you are
going to click on the button ‘1’ in the app the Bluetooth in the
mobile going to transfer that data to the other Bluetooth
available at the controller end. The message would be
transferred using serial communication. So the received
message is send to the controller through serial receive and
receives the information from serial transmit. So the received
information by controller is going to be compared with the inbuilt data and if it matches it turns ON the relay.
If the controller is going to receive the message like
“TURN OFF LIGHT”, it is going to turn the device OFF. By
using that we can also make different devices to interface with
the kit.
III.HARDWARE DESCRIPTION
It is main controller board which is going to control the device
according to the information received from the smart phone. It
consists of ARM LPC2148 controller to control the device. In
addition to that it also consists of relay to operate the 230V
A/C device.We are going to connect our bulb which works on
230 Volts. For the information to be transmitted from the
mobile to the kit we are going to use wireless technology that
is GSM.
GSM:
It is the one of the wireless technologies used to transmit the
data from one place to another. GSM works on narrowband
TDMA, which allows simultaneous eight calls at the same
time on the same radio frequency band. There is availability
of three frequency bands available. They are FDMA
(Frequency Division Multiple Access), TDMA (Time
Division Multiple Access), and CDMA (Code Division
Multiple Access). All these three frequency bands allow
multiple users to share the same physical channel.
The main working principle of this project is wireless
communication based on ZIGBEE, and to control the device

 14-channels ADC is available with 10-bit resolution.
TDMA:
It is Time Division Multiple Access where two or more
channels of information are transmitted over the same link by
allocating a different time interval for the transmission of each
channel. It also consists of a property called frequency
hopping. Hopping is nothing but jumping of call from one
frequency band to another.
CDMA:It is code division multiple access, whereit consist of
wide spread spectrum technology wherethe information
available in particular signal strength is further more increased.
This spectrum can be used by many other users to pass their
information.
RELAY:
 DAC with 10-bit resolution is provided.
 maximum clock frequency up to it works is 60 MHz
 1ms is the time taken to erase 256bytes and 400ms
for full erase.
 USB 2.0 is also available to perform the information
exchange.
 Conversion time required for analogue to digital will
be 2.44us.
 Two timers/external event counters (with four
capture and four compare channels and one PWM
channel and also watch dog timers) are also available.
 REAL TIME CLOCK is in-built with the dedicated
clock frequency up to 32 kHz.
 It is also provided with two UART’s and two fast I2C
bus and SSP, SPI with buffering and data length
capabilities.

BULB2
It is five terminals device, used to control the 230v A/C
supply. The phase is given at common pin or pole present at
the middle of the three pins. Remaining two pins are ‘A’, ‘B’.
One should be given at VCC supply and other pin should be
given to the micro controller. So according to the voltage
available at theterminal ‘B’, current will be transmitting
through the coil.
Internally it consists of the filament from the pole pin
to the NC when there is no supply at the terminals A, B.
Whenthe current passes through the terminals A, B, due to
magnetic flux generated around, the coil will be attracted to
the NO terminal.Thus the supply is passed to load which we
have connected to the relay.
Micro controller:
The controller here we are using is ARM (LPC 2148); it has
far better features than our basic controller.

It is Quadra-pack IC with 16 pins on all sides.

512 kb of flash memory is also in-built in our
controller.

Here the smart phone we using consist of android app. The
developed android app will consist of four buttons. Whenever
you are going to press any switch then a coded message is
generated, and that message is send to monitoring kit through
Bluetooth. Then the controller is going to verify whether the
received message is from pre-defined number or not. If the
message is from not the pre-defined number then that
messageis neglected. If the message is from pre-defined
number then it is going to check the msg. then according to
the message the device is controlled. But the Bluetooth range
is very short; it should be used with in the range. So in that
case we are going to use GSM module to perform the
operation.Here in our existing system a good choice to design
a terminal based on phone. The system is composed of
android Mobile phones. With the popularity of smart phones,
particularly, the phone based on Android system is rapidly
developed. It means that the remote control based on Android
phone will become a mainstream way. After logging into the
control interface, users can easily control the lights, TVs and
air conditionings anytime, anywhere, which brings great
convenience to people and improves the quality of life.

Here we are going to use smart phone to control the
home appliances such as bulb, fan etc. So to perform the
control operation we are going to develop an android app.
Here the app will be something like that it consists of
the display and four other buttons. Each and every button has
a coded message written in the back end. So whenever you are
going to click on the any of the button the back end message
would be transmitted from the mobile to the kit. Here to
transmit the information we are going to using message
balance from mobile in which the app is installed. So the
coded message will be transmitted to the GSM modem
arranged to the kit.
In the software we are going to feed the entire
messages that are going to be generated from the app. When
message has been received by the GSM modem and it will
send that message to controller. Then at the controller
received message would be compared with the each and every
fed message in it.
Then according to the received message we are going
to intimate the controller to do so and so work on the match of
the particular received message.
So by that we can perform the control operation of
fan or some other device. It can also be used as the security

purpose. Whenever you the individual want to control the
device, it is going to perform the string compare operation
with mobile number received. If the message received is from
some otherMobile number, then the string comparison will be
failed and that message will be discarded. Thus it is producing
security.Thus we have executed the project, by controlling the
different home appliances with the help of wireless
technology using GSM module and smart phone.
VI.CONCULSION
Here in this paper, we proposed a new type of
appliances control available at home,which performs the
action of control using wireless technology GSM.
