Abstract - The aim of the paper presents a design and prototype implementation of new home automation systemthatusesWi-Fi
technology as a network infrastructure connecting its parts. The proposed system is betterfromthescalabilityandflexibilitypoint
of view than the commercially available home automation systems. The AVR family microcontroller is used by our system for
processing all user commands. For the connection to the internet and to receive the user commands a Wi-Fi modem is used. WIFI
modem receives the commands which are sent through the internet. The received information is decoded bytheWi-Fi modemand
passed to the microcontroller. The microcontroller then takes necessary actions as per user’s commands. Thestateofthesystemis
displayed on the LCD display. Thus the entire industry is automated using online GUI for easy industry automation.

1. INTRODUCTION
Home automation system is getting popular and widely used in a lot of houses worldwide. It has tons of advantages to users
even more to the handicapped and/or elderly users in which it will make it easier for them to control their home appliances.
Home automation systems can be labeled to two medium in which how it is connected and they are either wired or wirelessly
connected. The main difference between these two kinds isthathomeappliancesarelinkedwirelesslya central controllerifita
wireless home automation system. On the other hand, the appliances are connected to a central controller if the medium use
wired communication method. Wireless system had been introducedinordertodisposeofwiredcommunicationamonghome
appliances[7]. IOT based, Bluetooth based home automation will be applied the order of reference in the running text should
match with the list of references at the end of the paper. Nowadays, everyone cannot be separated from their smartphones. a
number of five thousands individuals from USA, UK, South Korea, India, China, South Africa,Indonesia and Brazil took a survey
regarding which was done by Time magazine. The result proved most of them is inseparable from their smartphones, eighty
four percent allegedly claimed that survive without their smartphones[10].
The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects,animals
or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring
human-to-human or human-to-computer interaction. The InternetofThings(IoT)isthenetwork ofphysical objectsor"things"
embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange
data[1]. IoT allows objects to be sensed and controlled remotely acrossexisting network infrastructure,creatingopportunities
for more direct integration between the physical world and computer-based systems, and resulting in improved efficiency,
accuracy and economic benefit Home automation is computerization of the home, housework or household action.
Home automation may incorporate a control unit for controlling of lighting, HVAC (warming, ventilation and aerating and
cooling), machines, and different frameworks, to give enhanced accommodation,solace,better energysaving,productivityand
security. The idea of home Automation has been around for quite a while and items have been available for a considerable
number of years, however nobody’s arrangement has gotten through to the standard yet[2]. Home computerization for the
elderly and debilitated can give expanded personal satisfaction to persons who may generally need parental figures or
institutional consideration. It can likewise give a remote interface to home apparatuses or the automation system itself,
through phone line, remote transmission or the web, to give control andobserveand monitor bymeansofansmartphonesora
web explorer program.

2. PROPOSED WORK
IOT or internet of things is an upcoming technology that allows us to control hardware devices through the internet. Here we
propose to use IOT in order to control home appliances, thusautomatingmodernhomesthroughtheinternet.This systemuses
three loads to demonstrate as house lighting and a fan. Our user friendly interface allows a user to easily control these home
appliances through the internet[3]. For this system we use an AVR family microcontroller. This microcontroller is interfaced
with a Wi-Fi modem to get user commands over the internet.

Hardware components
ATMEGA-AT89S52
The AT89S52 comes from the popular 8051 family of Atmel Microcontrollers. It is an 8-bit CMOS microcontroller with 8K as
Flash memory and 256 bytes of RAM. Since it is similar to the trust worthy 8051 architecture thesemicrocontrollersareasper
industry standard. It has 32 I/O pins comprising of three 16-bit timers, external interrupts, full-duplex serial port, on-chip
oscillator and clock circuitry. The Microcontroller also has Operating mode, Idle Mode and Power down mode which makes it
suitable for battery operated applications. Few considerable drawback of the microcontroller is that it does not have in-built
ADC and does not support SPI or I2C protocols [4]. However you can utilize external modules for the same.

WIFI MODULE
ESP8266 is Wi-Fi enabled system on chip (SoC) module; It is mostly used for development of IoT (Internet of Things)
embedded applications. The chip first came to the attention of western makers in August 2014 with the ESP-01 module,made
by a third-party manufacturer Ai-Thinker. This small module allows microcontrollers to connect to a Wi-Finetwork andmake
simple TCP/IP connections using Hayes-style commands. However, at first there was almost no English-language
documentation on the chip and the commands it accepted[5]. The very low price and the factthattherewereveryfewexternal
components on the module, which suggested that it could eventually be very inexpensiveinvolume,attractedmany hackersto
explore the module, chip, and the software on it, as well as to translate the Chinese documentation.TheESP8285 isanESP8266
with 1 MB of built-in flash, allowing for single-chip devices capable of connecting to Wi-Fi[9].

AC LOAD (BULB)
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to
such a high temperature that it glows with visible light (incandescence). The filament is protected from oxidation with a glass
or fused quartz bulb that is filled with inert gas or a vacuum. In a halogen lamp, filament evaporation is slowed by a chemical
process that redeposit metal vapor onto the filament, thereby extending its life. The light bulb is supplied with electriccurrent
by feed-through terminals or wires embedded in the glass. Most bulbs are used in a socketwhichprovidesmechanical support
and electrical connections[6].

 Now the mobile is connected to the Wi-Fi module and can be operated through entering commands.
 The data sent from mobile to WIFI will be received by WIFI module connected to Micro controller.

 Thus the output loads can be controlled through mobile by entering the commands given below:-
 “*1” for turning ON the DC motor.
 “*2” for turning OFF the DC motor.
 “*3” for turning ON the LED lights.
 “*4” for turning OFF the LED lights.
 “*5” for turning ON the AC incandescent bulb.
 “*6” for turning OFF the AC incandescent bulb.
 By entering the command “*1” in the mobile, the “relay 1” connected to the DC motor will be switched ON and the
motor operates.

4. CONCLUSION
Earlier we used to monitor the things by using RFID system where it was only used for short distance communication. To
reduce the manual overhead, the thing which we are introducing is automation of industriesusinginternetofthingswhichcan
overcome the RFID shorter distance problem. Using IOT in industries we can monitor and control the industrial machineries
more easily
