Abstract
The home automation becomes important, because it gives the user the comfortable and
easily for using the home devices. The implementation and design of wireless home automation
control used two methods, WLAN technology and RF remote control handheld to control of the
selective home devices with integral security and protected system. The system is low cost and
flexible with the increasing variety of devices to be controlled.
The objective of this project is to enable users to remotely control their home appliances
and systems using a cell phone-based interface. To access the control unit, the user should send
an authentication code along with the required/desired function/action to his/her home control
system via GSM. Upon being properly authenticated, the cell phone-based interface at home
(control unit) would relay the commands to a microcontroller that would perform the required
function/action.

CHAPTER 1: Introduction
1.1 Problem Statement
The objective of this project is to develop a device that allows for a user to remotely
control and monitor multiple home appliances using a cellular phone. This system will be a
powerful and flexible tool that will offer this service at any time, and from anywhere with the
constraints of the technologies being applied. Possible target appliances include (but are not
limited to) climate control systems, security systems and lights; anything with an electrical
interface.
The proposed approach for designing this system is to implement a microcontroller based
control module that receives its instructions and commands from a cellular phone over the GSM
network. The microcontroller then will carry out the issued commands. For security purposes, a
means of identification and user authentication will be implemented, and will combine caller
identification with a password authorization.
1.2 Operating Environment
The control system will include two separate units: the cellular phone, and the control unit.
There will therefore be two operating environments. The cellular phone will operate indoors
and outdoors whereas the control unit will operate indoors.

1.3 Assumptions
The following is a list of assumptions for the project:
1. The user and control unit will establish communication via GSM.
2. All service charges from service provider apply.
3. The controlled appliances will have to have an electrical interface in order to be controlled
By microcontroller.
1.4 Review of related literature
This project has been made by several people, but no one has used DTMF technology for
controlling home appliances. They have used DTMF technology for different purposes but not
for controlling home appliances.
In our project we have used the auto answer facility which is present in many of the cell
phones today, so we escaped from designing the ring detector circuit.
1.5 Present Scenario
Possible customers for this product would be home improvement contractors, and supply
stores. The benefit of this is the end-product can be sold in large quantities and it can be
incorporated into the construction of modernize homes. The end-product will be not sold in
retails stores because reconfiguring of the end-product to control different electrical appliances
will be complicated and it should only be attempted by trained technicians. Retail stores would
also not be a good target for commercialization due to the system requiring a cellular phone
plan in order to operate. Advertising through cellular phone providers would be a more feasible
option.

CHAPTER 2: System Information
2.1 System Specifications
 An authenticated user can control eight home appliances from any remote place
having mobile phone network.
 Regulated power supply: 5V and 500ma.
 Relay: 230V AC
 The system requires two phones out of which the one present at the control unit has
to be a cell phone with auto answer facility.
 The system requires ATMEL microcontroller AT89S52 and DTMF decoder
MT8870D IC.
 It requires 16X2 LCD (Liquid Crystal Display) to display the device status.

2.2 Block Diagram
Figure 1. Block Diagram of System

2.3 Block Diagram Description
 Phone on the transmitting side:
The person who wants to switch on/off any device kept at the controller side calls
from a phone and, once the call gets picked up, enters the password and tones for a
corresponding device. Every key has to be pressed for a minimum amount of time to get
it latched at the decoder IC.
 Mobile phone on the receiving side:
The mobile phone on the receiver side picks up the phone automatically after
5seconds, and then makes the tones available to the DTMF tone decoder IC through the
headphone jack of the phone.
 DTMF Tone Decoder IC:
The DTMF tone decoder IC converts the received tones to their respective binary
values and then gives them as an input to the microcontroller.
The DTMF tone decoder IC’s internal architecture consists of a band split filter
section which separates the low and the high tone of the received tone pair, followed by a
digital decode(counting) section which verifies both the frequency and duration of the
received tones before passing resultant 4-bit code to the output bus. These 4-bits along
with a bit which validates a received tone are given as an input to the port1 of
microcontroller.

 The Microcontroller:
The five output bits of the decoder IC serve as an input to port 1 of the
microcontroller. Then each tone is verified by the programmed microcontroller and once
a correct sequence of code is received, output corresponding to the tones sent by the user
is made available at the port0, which is connected to relay through a relay driver.
 Relay Circuitry:
The output from the port0 of the microcontroller is given to the relay driver IC
which drives the corresponding relay, to which the home appliances are connected.
 Home Appliances:
One terminal of each appliance is connected to relay and the other terminal is
connected to 230v AC. As soon as the relay gets driven by the microcontroller the device
gets switched on/off.

2.4 System Flowchart:

Chapter 3: Working and Module Details:
3.1 System Working:
Home automation system automatically controls the home appliances when the
users are not able to access the devices physically. Microcontroller is the heart of the
system. The main technology used in the system is a DTMF (Dial Tone Multiple
Frequency). The system decodes the received code and gives the input to the
microcontroller. It generates the specific code according to saved program and controls
the connected home appliances. It also displays the device status on 16x2 LCD (Liquid
Crystal Display). Our system controls maximum eight devices. It is also possible to
connect more than eight devices. It is also possible to connect more than eight devices by
little modifications of the system.
In our system we have used AT89S52 microcontroller but it is also possible to use
another microcontroller. The working of DTMF decoder IC is explained in chapter 4 of
this report. We have used MCT2E optoisolator. It isolates the high voltage signal from the
sensitive system. So it prevents system damage. In the device driver circuit connection of
the two transistors provides current amplification. It is shown in the system schematic.
The diode connected parallel with the relay contacts provides a freewheeling of high
voltage. Hence it prevents the circuit from high voltage damage.

 Description:-
The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with
8K bytes of in-system programmable Flash memory. The device is manufactured using
Atmel’s high-density nonvolatile memory technology and is compatible with the
industry-standard 80C51 instruction set and pin out. The on-chip Flash allows the
program memory to be reprogrammed in-system or by a conventional nonvolatile
memory programmer. By combining a versatile 8-bit CPU with in-system programmable
Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller which
provides a highly-flexible and cost-effective solution to many embedded control
applications.
The AT89S52 provides the following standard features: 8K bytes of Flash, 256
bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, three 16-bit
timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-
chip oscillator, and clock circuitry. In addition, the AT89S52 is designed with static logic
for operation down to zero frequency and supports two software selectable power saving
modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial
port, and interrupt system to continue functioning. The Power-down mode saves the
RAM contents but freezes the oscillator, disabling all other chip functions until the next
interrupt or hardware reset.

 Pin Configuration:-
Figure 4. Pin Diagram of AT89S52

 Pin Description:-
VCC Supply voltage.
GND Ground.
Port 0 Port 0 is an 8-bit open drain bidirectional I/O port. As an output
port, each pin can sink eight TTL inputs. When 1s are written to port 0
pins, the pins can be used as high impedance inputs.
Port 0 can also be configured to be the multiplexed low-order
address/data bus during accesses to external program and data
memory.
In this mode, P0 has internal pull-ups. Port 0 also receives the code
bytes during Flash programming and outputs the code bytes during
program verification. External pull-ups are required during program
verification.
Port 1 Port 1 is an 8-bit bidirectional I/O port with internal pull-ups.
The Port 1 output buffers can sink/source four TTL inputs. When 1s
are written to Port 1 pins, they are pulled high by the internal pull-ups
and can be used as inputs.
As inputs, Port 1 pins that are externally being pulled low will source
current (IIL) because of the internal pull-ups. In addition, P1.0 and
P1.1 can be configured to be the timer/counter 2 external count input
(P1.0/T2) and the timer/counter 2 trigger input (P1.1/T2EX),
respectively, as shown in the following table. Port 1 also receives the
low-order address bytes during Flash Programming and verification.

Port 2 Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. The Port
2 output buffers can sink/source four TTL inputs. When 1s are written to
Port 2 pins, they are pulled high by the internal pull-ups and can be used as
inputs. As inputs, Port 2 pins that are externally being pulled low will source
current (IIL) because of the internal pull-ups.
Port 2 emits the high-order address byte during fetches from external
program memory and during accesses to external data memory that use 16-
bit addresses (MOVX @DPTR).
In this application, Port 2 uses strong internal pull-ups when emitting 1s.
During accesses to external data memory that use 8-bit addresses (MOVX @
RI), Port 2 emits the contents of the P2 Special Function Register.
Port 2 also receives the high-order address bits and some control signals
during Flash programming and verification.
Port 3 Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. The Port
3 output buffers can sink/source four TTL inputs. When 1s are written to
Port 3 pins, they are pulled high by the internal pull-ups and can be used as
inputs. As inputs, Port 3 pins that are externally being pulled low will source
current (IIL) because of the pull-ups.

Port 3 receives some control signals for Flash programming and verification.
Port 3 also serves the functions of various special features of the AT89S52,
as shown in the following table.
RST Reset input. A high on this pin for two machine cycles while
the oscillator is running resets the device. This pin drives high for 98
oscillator periods after the Watchdog times out. The DISRTO bit in
SFR AUXR (address 8EH) can be used to disable this feature. In the
default state of bit DISRTO, the RESET HIGH out feature is enabled.
ALE/PROG Address Latch Enable (ALE) is an output pulse for
latching the low byte of the address during accesses to external
memory. This pin is also the program pulse input (PROG) during
Flash programming. In normal operation, ALE is emitted at a constant
rate of 1/6 the oscillator frequency and may be used for external
timing or clocking purposes. Note, however, that one ALE pulse is
skipped during each access to external data memory. If desired, ALE

operation can be disabled by setting bit 0 of SFR location 8EH. With
the bit set, ALE is active only during a MOVX or MOVC instruction.
Otherwise, the pin is weakly pulled high. Setting the ALE-disable bit
has no effect if the microcontroller is in external execution mode.
PSEN Program Store Enable (PSEN) is the read strobe to external
program memory. When the AT89S52 is executing code from
external program memory, PSEN is activated twice each machine
cycle, except that two PSEN activations are skipped during each
access to external data memory.
EA/VPP External Access Enable. EA must be strapped to GND in order
to enable the device to fetch code from external program memory
locations starting at 0000H up to FFFFH.
Note, however, that if lock bit 1 is programmed, EA will be internally
latched on reset. EA should be strapped to VCC for internal program
executions. This pin also receives the 12-volt programming enable
voltage (VPP) during Flash programming.
XTAL1 Input to the inverting oscillator amplifier and input to the
internal clock operating circuit.
XTAL2 Output from the inverting oscillator amplifier.

LCD 16X 2 Modules
 Description:-
A liquid crystal display (LCD) is a thin, flat electronic visual display that uses the
light modulating properties of liquid crystals (LCs). LCs does not emit light directly.
They are used in a wide range of applications, including computer
monitors, television, instrument panels, aircraft cockpit displays, signage, etc. They are
common in consumer devices such as video players, gaming devices, clocks, watches,
calculators, and telephones. LCDs have displaced cathode ray tube (CRT) displays in
most applications. They are usually more compact, lightweight, portable, less expensive,
more reliable, and easier on the eyes. They are available in a wider range of screen sizes
than CRT and plasma displays, and since they do not use phosphors, they cannot suffer
image burn-in.
LCDs are more energy efficient and offer safer disposal than CRTs. Its low
electrical power consumption enables it to be used in battery-
powered electronic equipment. It is an electronically-modulated optical device made up
of any number of pixels filled with liquid crystals and arrayed in front of a light
source (backlight) or reflector to produce images in color or monochrome. The earliest
discovery leading to the development of LCD technology, the discovery of liquid
crystals, dates from 1888. By 2008, worldwide sales of televisions with LCD screens had
surpassed the sale of CRT units.

 Features:-
 It can be used to display corresponding characters in ASCII code.
 The module will automatically convert and display the data according to its
data type.
 255 steps backlight control.
 For continuous inputs, the module will carriage return automatically.
 Cursor position assignment and Tab function with configurable Tab steps
and HOME function.
 Destructive backspace, clear to end of line or end of screen from the cursor
position.
 Set the user defined characters to display various creative characters.
 Display off command to reduce power consumption.

Relay
Description:-
A relay is an electrically operated switch. Many relays use
an electromagnet to operate a switching mechanism mechanically, but other
operating principles are also used. Relays are used where it is necessary to
control a circuit by a low-power signal (with complete electrical isolation
between control and controlled circuits), or where several circuits must be
controlled by one signal.
 Operation:-
A simple electromagnetic relay consists of a coil of wire wrapped
around a soft ironcore, an iron yoke which provides a low reluctance path
for magnetic flux, a movable iron armature, and one or more sets of contacts
(there are two in the relay pictured).
The armature is hinged to the yoke and mechanically linked to one or
more sets of moving contacts. It is held in place by a spring so that when the
relay is de-energized there is an air gap in the magnetic circuit. In this
condition, one of the two sets of contacts in the relay pictured is closed, and
the other set is open.
Other relays may have more or fewer sets of contacts depending on
their function. The relay in the picture also has a wire connecting the
armature to the yoke.

This ensures continuity of the circuit between the moving contacts on
the armature, and the circuit track on the printed circuit board (PCB) via the
yoke, which is soldered to the PCB.
When an electric current is passed through the coil it generates a magnetic
field that activates the armature and the consequent movement of the
movable contact either makes or breaks (depending upon construction) a
connection with a fixed contact.
If the set of contacts was closed when the relay was de-energized,
then the movement opens the contacts and breaks the connection, and vice
versa if the contacts were open. When the current to the coil is switched off,
the armature is returned by a force, approximately half as strong as the
magnetic force, to its relaxed position.

CHAPTER 4: About DTMF
4.1 DTMF (Dial Tone Multiple Frequency)
DTMF stands for dual tone multiple frequency. DTMF is a term which used in
telephone industry. When any key on telephone or mobile phone is pressed one tone is
generated and it is audible which nothing but a DTMF tone is to decode DTMF tone
from mobile phone we need MT8870 DTMF decoder IC, 3.5mm male and female
connector.

4.2 What is DTMF code?
When any of the key like "1", "2", "*", "#" etc is pressed particular code is
transmitted. This code is consisting of two frequencies among which one is higher
frequency and second one is lower frequency. Following table shows the combination of
frequency for respected keys.
According to above table "8" is combination of lower frequency of 852 Hz and higher
frequency of 1336 Hz and "#" is of lower frequency of 941 Hz and higher frequency of
1447 Hz. So this is all about DTMF code, now let see about how DTMF code are
generated, transmitted and Decoded in mobile phone system. Here i am only talk about
GSM system.

4.3 Transmission of DTMF code in GSM network
In GSM networks so many channels are available but mainly there is only two
channels...
1) Physical Channels
2) Logical Channels
DTMF code are transmitted in FACCH i.e. fast associated control channel. Complete
hierarchy of FACCH is given below
FACCH is a bidirectional channel i.e. uplink and downlink. It is used to transmit and
receive emergency controlling signal messages. When any data or message need to be
transmitted through this channel, it will replace the voice signal to digital signalling data
for very short amount of time.

4.4 Decoding DTMF code
When any DTMF code has been received at mobile phone it can be audible
through speaker. So to decode this DTMF code speaker output it self can be used. Output
of speaker is connected to IC MT8870 which is DTMF decoder IC. It used widely to
decode DTMF code. It gives 4-bit digital output q1, q2, q3, and q4 according to the
received key. Following table shows the equivalent digital output for each key.

4.5 Connection Diagram

4.6 Splitter and Its Connection with Landline Phone
Splitter is used to split the single line into two separate lines. It is same as the
device that we use for landline.

CHAPTER 5: Conclusion & Future Scope
5.1 Conclusion
The project has been developed by integrating features of all the hardware components
used. Presence of every module has been reasoned out and placed carefully thus contributing to
the best working of the unit. Using highly advanced IC’s and with the help of growing
technology the project has been successfully implemented. Finally we conclude that “HOME
AUTOMATION” is an emerging field and there is a huge scope for research and development.
5.2 Future Scope
This product is aimed toward average consumers who wish to control household
appliances remotely from their cell phones provided that the appliances are electrically
controllable. Example of feasible appliances and applications under consideration include;
enable/disable security systems, fans, lights, kitchen appliances, and heating/ventilation/air
conditioning system.
Right now we have designed the project for control of eight devices but it can be
designed for more number of devices. It can be further expanded with a voice interactive system
facility. A feedback system can also be included which provides the state of a device (whether it
is on/off) to the remote user.
