– This project is based on the construction of a model simulating a home automation with different operation modes which
can be controlled also by Ethernet. To achieve this objective, a scale house that captures different signals, both digital and analog, has
been developed. To approach the house to a real web server can be implemented in a device in your own home connected to your pc
via a local area network. To capture the signals, the prototype has temperature, lighting, for the regulation and control. The core is
an Arduino uno board that allows the application operation and receives, from a web server, operating modes commands and, if it is
operating manually, orders to individually controls the different actuators. For the data transmission from the Arduino to the web
server, is used communication via Ethernet.
Keywords: Home automation, Arduino uno, Ethernet,Web Server.
I. INTRODUCTION
The main aim of this project is to implement a Home
automation console that can be easily accessible from distant
places through a simple web server running inside the home.
The basic functionalities in this proposed system includes
automatic control of Lights and other electrical / electronic
appliances. Internet-enabled hardware products are slowly
becoming popular. A real web server can be implemented in a
device in your own home connected to your pc via a local area
network. This will allow you to do things like display
temperature, control heater/geyser and switch light/fan
remotely from any web browser in the house. Arduino uno
based devices used at residential locations for the purpose of
home automation such as TV ON/OFF control, speed control
of fan, lighting control etc. Arduino uno communicate with
each other via Ethernet a wired communication. Because
thesesystems use hard-wired Ethernet, communication
between components is reliable and fast.
II. ARDUINO UNO BOARDS
A micro-controller is a small computer on a single integrated
circuit Containing aprocessor core, memory, and
programmable input/output peripherals The important Part
forus is that a micro-controller contains the processor (which
all computers have) and memory,and some input/output pins
that you can control. (often called GPIO –General Purpose
Input Output Pins)
The board contains everything needed to support the
microcontroller; simply connect it to a computer with a microUSB cable or power it with a AC-to-DC adapter or battery to
get started. The Due is compatible with all Arduino shields
that work at 3.3V and are compliant with the 1.0 Arduino pin

IV. HARDWARE IMPLEMENTATION
A. System Architecture
The proposed Ethernet Based Home Appliances Control
system architecture consists of PICMicrocontroller, Ethernet
Controller-W5100, Relay Board.
B. Operation
This section explains the operation and interfacing of each
modules present in the Ethernet Based Home Appliances
Control system architecture.The whole circuit can be divided
into following sections:-
1) Power supply modules:
This module is basically designed to achieve 12V, 1A and
5V, 500Ma and 3.3V. The design consists of a transformer
which is used to step down the AC voltage, IN4007 diodes
used to form a bridge rectifier to convert AC to DC, capacitor
1000uF which used as a filter circuit, 7812 regulator to obtain
a 12V DC and followed by 7805 regulator to obtain a 5V DC,
at the output of the regulator a 330 ohm resistance and LED is
connected as Power ON indicator. LT1086CT (3.3V) regulator
is used to generate 3.3V which is required for Ethernet
Controller is as
3) Ethernet Controller:
The Arduino Ethernet Shield V1 allows an Arduino board to
connect to the internet. It is based on the Wiznet
W5100ethernet chip (datasheet). The Wiznet W5100 provides
a network (IP) stack capable of both TCP and UDP. It
supports up to four simultaneous socket connections. Use
the Ethernet library to write sketches which connect to the
internet using the shield. The ethernet shield connects to an
Arduino board using long wire-wrap headers which extend
through the shield. This keeps the pin layout intact and allows
another shield to be stacked on top.
The most recent revision of the board exposes the 1.0 pinout
on rev 3 of the Arduino UNO board. The Ethernet Shield V1
has a standard RJ-45 connection, with an integrated line
transformer and Power over Ethernet enabled. There is an
onboard micro-SD card slot, which can be used to store files
for serving over the network. It is compatible with all the
Arduino/Genuino boards. The on-board micro SD card reader
is accessible through the SD Library. When working with this
library, SS is on Pin 4. The original revision of the shield
contained a full-size SD card slot; this is not supported. The
shield also includes a reset controller, to ensure that the
W5100 Ethernet module is properly reset on power-up.
Previous revisions of the shield were not compatible with the
Mega and need to be manually reset after power-up.

In this project, the results of the proposed system to control
the devices over internet through Ethernet connectivity using
Arduino Uno microcontroller is presented. Figure x shows the
login page which we designed using HTML language as a
home page, after entering the embedded web server IP address
(192.168.XX.XXX). Once the home page is loaded, the user
need to provide username and password to facilitate the
further access to control home appliances. This ensures the
security feature to user access. In the proposed system four
Lights are considered for demo purpose Load. After login, the
next control webpage as shown in figure x, on this page we
can control 3 devices just by clicking the menus on the web
page, initially all Lights, will be in off State i.e., „0‟ state is as
shown in figure 3.
Here, on this web page we are controlling Light, just by
clicking the light menu on the webpage as shown in the figure
9, initially Light State =„0‟ now the state changed to „1‟ and
also we can see the light ON state on the hardware design
module.
VI. CONCLUSION
In this paper we presented concepts and a prototype system for
home automation which can fit into a home appliance using
Ethernet. Internet-enabled hardware products are slowly
becoming common place. Ethernet‟s potential as a network for
distributed measurement and control is virtually unlimited. As
Ethernet provides inexpensive, relatively high speed network
access to individual users and low delay that can support many
applications. Ethernet continues to be enhanced with greater
performance, higher determinism, and lower cost
implementations and even consolidate control network
applications. A real web server is implemented in a device in
your own home, which is connected to your pc via a local area
network. If we compared Ethernet Technology with other
technologies like Bluetooth, Zigbee, IR, RF-ID and GSM, it is
having low response time, having very high speed, secured
and also reliable. In future the separate embedded web server
can be designed with Wi-Fi and Ethernet, which is coexistence technology on a single-chip.
