Introduction to the Topic
Automation is the process of automatically performing everyday functions around
the home to save you time, energy, money and at the same time offering improved
security.
The automation’ is performed by a central controller. This can be either a
standalone unit or a piece of software on a PC. Both options have their
advantages. The controller can carry out a number of functions:
Objectives
Home Automation Saves Money by lowering your monthly utility bills with the
remote & scheduled control of lights, appliances, sprinklers and your air
conditioning
 Never walk into a dark home again.
 Have the porch light automatically turn on when you open the front
door after dark. Lighting and audio controls can make a vacant home look
and sound occupied.
 You could set your Omni home control system to automatically call
you at work when your child comes home from school and keys in his
security code into the security system.
 Call your home control system over the phone to make changes to
your system.
 Log into your home control system over the Internet via Snap-Link or
Web-Link II and change your temperature settings.
 Set the temperature setting on your Omnistate to automatically turn
up when the security system is armed in the morning. It is then

automatically turned down one-half hour before you normally get home in
order for you to arrive home to a comfortable house.
 If you are leaving early from work, you can call into your home
control system to manually set the temperature to where you want it to be
when you get home.
Basic idea of Home automation using Telnet is conceived
from router configuration. As we use a remote terminal to access router instead of
console to configure it, we have used the same way to control our controller
instead of router to control our Home Appliances. The controller 89c51 which is
programmed such as that when it receives the command through Telnet it
processes on it and turns ON or OFF the appliance as per command receive.
Telnet server is used for interfacing. Server connects controller with telnet remote
PC through serial port i.e. DB9 and connects controller with remote pc through
internet medium i.e. TCP/IP.

Different Home Automation Appliances
1- Heating, Ventilation and Air Conditioning
Heating, Ventilation and Air Conditioning solutions include temperature and
humidity control (climatic). This is generally one of the most important aspects to
a homeowner. An Internet-controlled thermostat, for example, can both save
money and help the environment, by allowing the homeowner to control the
building's heating and air conditioning systems remotely.
2- Lighting
Lighting control systems involves aspects related to controlling electric lights.
• Extinguished general of all the lights of the house
• Automation of switched off / ignition in every point of light
• Regulation of the illumination according to the level of ambient luminosity
3- Natural lighting
Natural lighting control involves controlling window shades, LCD shades,
draperies and awnings. Recent advances include use of RF technology to avoid
wiring to switches and integration with third party home automation systems for
centralized control.
4- Audio
Major companies associated with Audio Distribution include: There are three
components that allow the consumer to listen to audio throughout your home, or
business:
5

6. GSM CONTROLLED HOME AUTOMATION SYSTEM
o Cat 5e/CAT 6 cable from Audio central unit.
o 2 sets of speaker cabling (4ply from amplifier, and 2 ply from key
pad to ceiling or wall speakers).
o A keypad to control your volume and sources.
This category includes audio switching and distribution. Audio switching
determines the selection of an audio source. Audio distribution allows an audio
source to be heard in one or more rooms. This feature is often referred to as 'multi-
zone' audio.
5- Video
This includes video switching and distribution, allowing a video source to be
viewed on multiple TVs. This feature is often referred to as 'multi-zone' video.
Integration of the intercom to the telephone, or of the video door entry system to
the television set, allowing the residents to view the door camera automatically.
6- Security
Control and integration of security systems.
With Home Automation, the consumer can select and watch cameras live from an
Internet source to their home or business. Security cameras can be controlled,
allowing the user to observe activity around a house or business right from a
Monitor or touch panel. Security systems can include motion sensors that will
detect any kind of unauthorized movement and notify the user through the security
system or via cell phone.
This category also includes control and distribution of security cameras
• Detection of possible intrusion
o sensors of detection of movement
o sensors of magnetic contact of door/window
o sensors of glass breaking
o sensors of pressure changes
• Simulation of presence.
• Detection of fire, gas leaks, water leaks (see fire alarm and gas alarm)
• Medical alert. Teleassistance.
• Precise and safe closing of blinds.

7- Intercoms
An intercom system allows communication via a microphone and loud speaker
between multiple rooms.
• Ubiquity in the external control as much internal, remote control from the
Internet, PC, wireless controls electrical equipment.
• Transmission of alarms.
• Intercommunications.
Using special hardware, almost any device can be monitored and controlled
automatically or remotely.
8 - Plant Watering
 Pool pump(s) and heater, Hot tub and Spa
 Sump Pump (need info and links)

Project Featutres
• It provides many functions (CPU, RAM, ROM, I/O, interrupt logic, timer,
etc.) in a single package
• 8-bit ALU, Accumulator and 8-bit Registers; hence it is an 8-bit
microcontroller
• 8-bit data bus - It can access 8 bits of data in one operation
• 16-bit address bus - It can access 216 memory locations - 64KB (65536
locations) each of RAM and ROM
• On-chip RAM - 128 bytes (data memory)
• On-chip ROM - 4k Byte (program memory)
• Four byte bi-directional input/output port
• UART (serial port)
• Two 16-bit Counter/timers
• Two-level interrupt priority
• Power saving mode

Benefits of the Project
Most controllers will offer all of the above plus more. When you use controllers
connected in the appropriate fashion, you can realize all sorts of benefits, limited
primarily by your imagination.
For example:-
• When on holiday or working late, have the lights come on automatically
and draw the curtains.
• Set room moods, i.e. one button push to switch off the main light, dim the
perimeter lights and switch the surround sound system on ready to play a
movie.
• At dusk, check that the garage door is closed.
• Switch on the electric blanket whilst you're sitting on your sofa.
The controller can be either standalone or combined into
a security system to give additional benefits.
Applications
An automated home is about the convenience of saving your time and effort by
having your home automatically do routine functions such as watering your grass
(but only if it has not rained recently), or turning off all lights, setting the
thermostat to economy mode and arming the security system when you retire for
the night.

Future Work of the project:
The system being developed will focus an automating security and electronic
appliances for homes and offices. This involves providing the feature of tracking
the status of appliances and manipulating them accordingly. It also involves
monitoring and remotely the security related events. The scope is also consists of
sending remote messages to the user by any means. The proposed security and
home/office automation system will also focus on user remote system connectivity
so that it can be manage by the user when he/she is outside.
It also comes in boundary of the system, to detect unwanted motions through
different intruder devices and maintain passed activities and event logs. The
system will target on controlling other home and office processes which are being
perform manually, controlling doors can be one of those processes and also will
target on modern connectivity technologies to minimize the failure chance. The
proposed system will also subject on controlling home and office electricity flow
remotely from different locations.
• The system can be easily connected to the personal computer for further
control.
• Energy efficiency at various places like house, offices, schools, colleges etc
can be enhanced .
• By performing certain modifications in the project, a different level of
energy conservation can be achieved.
