Application of Zigbee in Smart Home with Dynamic Routing AlgorithmNooria Sukmaningtyas
In order to avoid damaging the walls and bore a hole through the walls, also to save the cost of
rewiring, low voltage power line can be used to implement the smart home. However, several difficult
problem must be solved at the same time , the most important are finding a technology method to
suppress the noise interference and resist the weaker signal. The smart home system is introduced in the
paper. During the design of Smart Home System adopting power line signal carrier, a dynamic routine
algorithm based on the idea of Genetic Algorithm is proposed to cope with the time-varying and random
feature of power line channel. Thus the system can find the transmission path in real time and dispatch the
signal carrier to transmit among the nodes. With this algorithm, the communication between a certain
group-controller and its terminal nodes or between the main-controller and the group-controllers is realized
successfully. In the proposed algorithm all nodes but the controller adopt same driver, therefore the plug
and play is realized for all nodes.

Abstract
This paper mainly focuses on using wireless technology effectively for security. The system is SMS-based and uses wireless
technology to revolutionize the standards of living. It uses a GSM Modem to send an SMS to the home owner in case of an
intrusion. The project is realized by interfacing an infrared trans-receiver with an ATMEGA16 microcontroller and a GSM
Module. As the system uses GSM technology, it provides ubiquitous access to the system for security.
Index Terms: GSM, ATMEGA16, Home automation, GSM SIM 300.
I. INTRODUCTION
We have come across various equipments in the
market used to prevent an intrusion. These
equipments use reinforced steel, digitized codes,
double bolted locks etc. The purpose of such products
is to prevent intrusion or robbery from the very
beginning. These commercial products are isolated
objects i.e. if you want to protect a room you have to
buy the entire door. Also, if in any case an intrusion is
made, these products can’t do anything after. Due to
the commercialization and isolation of products, they
are heavy and expensive.
We have tried to overcome these drawbacks by
implementing a home security system which includes
an IR sensor, ATMEGA16 board, GSM Modem and
a Relay circuit. When a person cuts through the
infrared beam, an interrupt is sent to the
microcontroller which is further interfaced with a
GSM module. It sends an SMS to the home owner to
alert him/her. The basic flow of this system is shown
in Figure:1. Thus, this project takes some action after
the intrusion has already taken place, unlike the
systems usually seen in the market.
The home automation system gives the user the
flexibility to activate or deactivate the system simple
by using an SMS which includes a pre-decided code.
The system also allows the home owner to
dynamically transfer the authority to control the entire
device. This system is portable, easy to install,
reasonably priced and can be used in any
environment.
Figure 1: Block Diagram of Entire System
II.INFRARED TRANSRECEIVER
An infrared (IR) transceiver, sends and receives
infrared data. The device may either have a focused
beam, thus requiring it to be in a precise position in
order to function properly, or it may be a broader
beam, depending on the applications that it is
designed for.
The IR transreceiver board used in this system
includes IC 555, IR LED and TSOP1738 IR
Receiver. The IR LED transmits an infrared beam,
which does not get reflected back unless there is an
object, or in this case, an intruder cutting the beam.
The range of the IR LED in this project is 15cm. If
the beam is reflected back, then it is received by
TSOP1738, which is an active low device i.e. it sends
a high signal to the microcontroller unless it receives
a reflected beam. A 5V supply is given to power up

this board. Data is transferred at a rate of up to
2400bps. The PCM carrier frequency of TSOP1738
is 38KHz.[8][9] This board and the IR Receiver is

III. ATMEGA16
MICROCONTROLLER
ATmega16 is an 8-bit microcontroller which
delivers high performance at a low power
consumption rate. It has an advanced RISC (Reduced
Instruction Set Computing) architecture with 131
instructions that mostly execute in one machine cycle.
The maximum frequency of operation is 16MHz at
4.5V.
It has 16KB of in-system self-programmable
flash program memory, 1KB of internal static RAM
and 512 bytes of internal EEPROM. It has a data
retention capacity of 20 years at 85ºC and 100 years
at 25 ºC.
The microcontroller is a 40 pin IC out of which
32 pins are programmable I/O ports. These ports are
divided into four groups of 8 pins each called
PORTA, PORTB, PORTC and PORTD. The IC and
its pin configuration are shown in Figure 2.
Figure 2: Pin Configuration of ATmega16
The operating voltage range for the ATmega16
microcontroller is 2.7V - 5.5V. [1][2] In this system a
12V adaptor is used to supply power. This input
power is fed to a Voltage regulator - LM7805 which
gives an output of 5V. This is then supplied to the rest
of the circuit. The microcontroller board also includes
a reset pin, a power LED, serial port using MAX232.
MAX232 is an IC which converts signals from RS232
serial port to signals suitable for TTL compatible
digital logic circuits.[3] This circuit is shown in
Figure 3.
Figure 3: ATmega16 Board
The microcontroller is programmed by using the
TopWin6 software. A hex file, generated using
ATMEL Studio 6.2 is loaded into the driver and then
fed into the IC. Embedded C is the language used to
program the IC.
IV. GSM MODEM
GSM (Global System for Mobile
Communication) is a wireless network system that
uses a mobile operator and functions just like a
mobile phone. The GSM modem has a SIM card slot,
thus giving the modem a mobile number of its own
and enabling it to activate communication over the
network. The user can send or receive an SMS as well
as make or receive voice calls over the modem
interface.
The GSM modem may be connected to a
computer directly through the serial port or to a
microcontroller using RS232. Thus the modem can
be used to develop embedded applications. [4] There
are a set of AT commands that are used to establish
communication between the microcontroller and the
GSM modem.
The GSM modem used in this home security
system uses SIM300 module. It has a power and
network LED making it convenient to debug. There is
also a wire antenna on the modem to provide better
reception. SIM300 has an adjustable baud rate of
1200-115200bps. However, in this system it is set to
9600bps. The GSM modem consumes only 0.25A
during normal operation and about 1A during
transmission. Thus, it has very low power
consumption. The operating voltage range is 7-
15V.[5]

www.ijera.com 145 | P a g e
The ubiquity and low cost of implementation of
the GSM standard makes it the ideal communication
medium for a low budget home automation system.
The GSM modem used in this device is shown in
Figure 4.
Figure 4: GSM Modem using SIM300 module
V.RELAY BOARD FOR DEVICE
The type of relay used in this Home Security
system is a Solid-State Relay (SSR). An SSR is
basically an electronic switching device. Whenever
an external voltage, over a certain threshold, is
applied across its control terminals, a magnetic field
is generated which attracts a movable lever, thus
establishing a flow of current and switching it ON. It
then switches this power to a load circuitry. Thus, it
performs the function of an electromechanical switch
without any mechanical parts.
The relay board includes ULN2803 IC which is
an 8 channel Darlington driver, a relay, 3 pin PBT
connector, IN4002 diode, 1K resistor and an indicator
LED. The relay used in this system is JQC-3FC/T73
working at 12V DC which is shown in Figure 5.. The
maximum switching current for the relay is 7A-10A
and the maximum switching voltage is 28V DC or
250V AC.[6][7]
Figure 5: Relay JQC-3FC/T73
The relay board used in the system is used to
drive a camera. The camera is placed at such an
angle, that when it is triggered by the relay, it takes a
snapshot of the intruder and sends the same to the
microcontroller. The implementation of a camera in
the circuitry is a future prospect of the project. The
relay board is shown in Figure 6.

During the course of the project, we came across
several problems that were a hindrance to the
appropriate functioning of the system. There were
hardware as well as software issues. Of the many
problems encountered, some of them are listed below.
A. Complication with the GSM Modem:
A 12V/1A adaptor is needed to power up a GSM
modem. After inserting a valid SIM card in the SIM
card slot, the GSM catches network which is
indicated by a network LED on the GSM Modem. It
is also connected to a tested microcontroller via a
serial communication port.
However, inspite of having network, the GSM
Modem was unable to send an SMS to the pre-coded
user.
B. Conflict in the ATmega16 Memory:
On programming the microcontroller, the
numbers to which the SMS needs to be sent to are
stored in the stack and the SMS' are stored in the
GSM message storage area. On powering up the
system, the GSM modem sends a message to the user
- 'Home Security Powered Up' which is an indication
that the system is active.
On sending an SMS to the GSM modem to carry
out any specific function, the GSM wasn't responding
to the same.

C. Soldering:
After testing the circuit on a bread board and
obtaining the desired results, we made the PCB layout
and soldered the components.
The final circuit board however was not working.
VII. PROPOSED PROBLEM SOLUTION
So as to ensure proper functioning of the system,
the problems mentioned above were overcome as
follows.
A. Solution for GSM Modem:
The GSM Modem can be connected to the
microcontroller as well as to the computer directly
through a serial port. We connected the Modem to the
computer for debugging. The working of the GSM
Modem can be tested using the software Terminal
v1.9b. On typing the command 'AT' in the command
window, the terminal replies 'OK' which indicates the
proper functioning of the GSM Modem. However, the
terminal was not responding to this command.
In order to overcome this problem, we used a
12V/2A adaptor. This extra current, gave the Modem
the boost necessary for proper functioning. After this,
we switched back to the initial adaptor i.e. 12V/1A
adaptor and the GSM Modem started functioning
normally. The terminal responded with 'OK' and then
showed all the AT commands being exchanged
between the microcontroller and the Modem
thereafter.
B. Solution for ATmega16 Memory:
The messages previously sent to the number in
the modem occupied the memory. Thus, the new
messages were getting discarded as the memory was
full.
In order to overcome this problem, a few changes had
to be made in the program code. Every time the
Home Security System is powered up, the first task
carried out is deleting all the previous messages from
the memory. This makes space for new messages thus
enabling the microcontroller and the GSM Modem to
respond to the same.
C. Solution to the Soldering Issue:
On testing the connectivity and the current flow
in the soldered circuit with the help of a multimeter,
we observed that a certain capacitor wasn't soldered
properly. Opposite polarity had been soldered due to
which the current reaching the IC exceeded the
necessary level thus, spoiling the IC.
Therefore, we had to resolder the capacitor and
replace the IC for the proper functioning of the
circuit.
VIII. SYSTEM WORKING
When the system is powered up, the GSM
Modem memory is cleared using the command
'AT+CMGD' so as to make space for the new
messages. The command 'AT+CMGF' is used to set
the GSM Modem to text mode in order to send and
receive the messages.
The GSM Modem sends a message "Home
Security Powered Up' to the home owner. This is
done by first reading the message from the GSM
message storage area using the command
'AT+CMGR' and then sending the same using the AT
command 'AT+CMGS'. This acts as a confirmation to
the home owner, that the system is functional.
Every time a certain entity cuts the IR beam, The
reflected signal is received by the TSOP1708 IR
Receiver. This being an active low component, sends
a low signal to the microcontroller on PortD-2 (i.e.
PD2). When the microcontroller receives this
interrupt from the IR Transreceiver Module, it uses
the command 'AT+CMGS' and commands the GSM
Modem to send the message 'Intrusion Detected' to
the home owner.
The home owner can dynamically control the
working of the system by sending an SMS to the
GSM Modem. When the Modem receives an SMS
from the user, it gets stored in the message storage
area and uses the same command mentioned above to
read it.
The microcontroller enables or disables the IR
Transcreceiver depending on the command sent by
the user. Whenever an intrusion is detected, along
with sending an SMS to the home owner, the
microcontroller also triggers the relay which can be
used to switch on the camera to take a picture of the
intruder.

Different parameters are taken into consideration
for the operation of the system. They are as follows:
1. Speed - We have specifically given a delay of
50ms so that an interrupt is not sent multiple
times for the same intruder.
2. Range - The range of the IR sensor in our project
is 15cm, which can be easily improved by
replacing the IR sensor
3. Height - The device needs to be placed at an
appropriate height so that an intruder cannot
avoid the beam by going above or below it.
X.CONCLUSION
In this project, a low cost, user-friendly, simple,
secure and universally acceptable solution for home
security has been introduced. This approach has
achieved the target to control the device remotely
using an SMS-based system satisfying user needs and
requirements. The system is cost-effective as
compared to the previously existing systems in the
market and can be easily implemented with high
reliability and security. The basic level of home
security control and remote monitoring has been
implemented. The system is extendible and more
levels can be further developed. Hence, we can
conclude that the required goals and objectives have
been achieved.
