5. Abstract
Traditionally electrical appliances in a home are controlled via switches that regulate the
electricity to these devices. As the world gets more and more technologically advanced,
we find new technology coming in deeper and deeper into our personal lives even at home.
Home automation is becoming more and more popular around the world and is becoming
a common practice. The process of home automation works by making everything in the
house automatically controlled using technology to control and do the jobs that we would
normally do manually. Home automation takes care of a lot of different activities in the
house.
The main objectie of this project is that we are controlling our home appliances using a
simple ciruit. That ciruit consist of a IR module.That receive the signal from our TV/VCD
remote. Output of that sensor goes to the clk of IC4017 that is used to shows the status of
our home appliances either in on/off state. Output of the IC is given to transistor which
amplifes the signal and then through a diode.
The appliance to be controlled is connected between the pole of the relay and neutral
terminal of mains. It gets connected to live terminal of AC mains via normally opened
(N/O) contact when the relay energises.

Introduction
The aim of the proposed system is to develop a cost effective solution that will provide
controlling of home appliances remotely and enable home security against intrusion in the
absence of homeowner. The home appliances control system with an affordable cost was
thought to be built that should be providing remote access to the appliances and allowing
home security. Though devices connected as home and office appliances consume electri-
cal power. These devices should be controlled as well as turn on/off if required. Most of
the times it was done manually. Now it is a necessity to control devices more effectively
and efficiently at anytime from anywhere.
In this system, we are going to develop a remote control based home/office appliance.
Remote control for home appliances is an absolute necessity in our fast-paced life. As
a result, much important has been given to this aspect and a range of remote controls
are prevalent today. One of the most common is that which makes use of IR radiations
at particular frequencies. Our product is a Remote Operated Home Appliance or Remote
controlled Home appliance. The circuit is connected to any of the home appliances (lamp,
fan, radio, etc) to make the appliance turn on/off from a TV, VCD, VCR, Air Conditioner
or DVD remote control. The circuit can be activated from up to 10 meters. It is very easy
to build and can be assembled on a general-purpose PCB.
For this purpose we mke a circuit that consist of a IR module, CD4017 IC, LEDs to
indicate the reception of the IR radiations, otherwise indicating the ON/OFF state, relay
and other components

Design Overview
Our idea comes into the reality by this circuit diagram. The circuit diagram is given
below:-
Figure 1: Circuit diagram for the Remote Control based Home Appliances[1]
1 Circuit Description
The circuit consist of two parts:-
• Transmitter
• Receiver

11. 1.1 Transmitor
The product consists of a remote which is the transmitter of the IR radiations. The circuit
diagram is given below:-
Figure 2: Transmitor for the Remote Control based Home Appliances
1.2 Receiver
Which responds to the radiations and switches ON and OFF the appliance.

Working of the Circuit
Connect this circuit to any of your home appliances (lamp, fan, radio, etc) to make the ap-
pliance turn on/off from a TV, VCD or DVD remote control. The circuit can be activated
from up to 10 metres[1].
0.3 Working of the IR module
• The 38kHz infrared (IR) rays generated by the remote control are received by IR re-
ceiver module TSOP1738 of the circuit. Pin 1 of TSOP1738 is connected to ground,
pin 2 is connected to the power supply through resistor R5 and the output is taken from
pin 3.
Figure 4: TSOP 1738
• The output signal is amplified by transistor T1 (BC558).
4

13. 0.4 IC CD4007
• The amplified signal is fed to clock pin 14 of decade counter IC CD4017 (IC1). Pin 8
of IC1 is grounded, pin 16 is connected to Vcc and pin 3 is connected to LED1 (red),
which glows to indicate that the appliance is off.
• The output of IC1 is taken from its pin 2. LED2 (green) connected to pin 2 is used to
indicate the on state of the appliance[8].
Figure 5: IC CD4007
0.5 Diode IN4007
• Diode 1N4007 (D1) acts as a freewheeling diode.
• A freewheeling diode is put into a circuit to protect the switching device from being
damaged by the reverse current of an inductive load(relay).
0.6 Relay
• The appliance to be controlled is connected between the pole of the relay and neutral
terminal of mains. It gets connected to live terminal of AC mains via normally opened
(N/O) contact when the relay energises.
• In short we can say relay is like a switsh which is necessary to control a circuit[9].

breadboard. The two diagram shows how we implement the cicuit on the breadboard.

Conclusion
The power line devices to control from the radio waves was a unique study, which concen-
trated on finding out how a smart home we have considered would function in everyday
life and what kinds of functionality it should provide to its users. This practical study
revealed results that have been discovered in theoretical laboratory tests successfully. It
would seem that the most desirable functions of a smart home are indeed various user
interfaces that allow more flexible control of the home. The home should also contain
learning and adaptive functions,which would gradually allow users to leave some func-
tions to the Home Controller.
• However as long as there are no compatible devices in the market it seems that there is
a long way to go before smart homes really become commonplace. After this study the
smart home instrument still continues at the university laboratory for development. In
this paper work the power line devices are controlled from wireless technology.
• Such intelligent instruments are very much helpful for the old and disabled persons. It
also helps to minimize the energy consumption. Another important application of this
instrument is it can control appliances from anywhere around the 10 meter periphery
and very much compatible and easy to handle by any age persons.
• However there are limits on what each interface can do and usually some functions
remain unavailable. Another practical obstacle becomes obvious when installing net-
works and devices in older buildings. Even wireless networks require power cabling
and equipment need their own installation space. In cases like these it is advantageous
9

18. to use existing cabling (phone and power lines, cable ducts etc.) as much as possible.

19. Chapter 7
Futuristic use of Instrument
• This is a very smart and intelligent instrument useful for all the age groups and has
a variety of uses in almost all the areas where instruments need to be automated and
controlled as per the human need and enhance facility.
• This instrument is basically to regulate and overcome all the obstacles for control over
the instrument.
• This instrument is basically to regulate and overcome all the obstacles for control over
the instrument. It is possible that the operating range and the instrument operability in
terms of number of instruments can be increased.
• It can be used in the case of a number of devices and applications such as TV, VCR,
camera, CD speller, radio, lamp, fan, music system or even tasks such as simply open-
ing a door.
• A single remote control can be made to operate at different frequencies, each cor-
responding to a particular task to be performed by the appliance, for example tele-
vision. This is a further application where a compact device can perform multiple
operations[10].
