3. INTRODUCTION
Homes of the 21st century will become more and more self-controlled and automated due to the
comfort it provides, especially when employed in a private home. A home automation system is a means that
allow users to control electric appliances of varying kind. Many existing, well-established home automation
systems are based on wired communication. This does not pose a problem until the system is planned well in
advance and installed during the physical construction of the building. But for already existing buildings the
implementation cost goes very high. In contrast, Wireless systems can be of great help for automation systems.
With the advancement of wireless technologies such as Wi-Fi, cloud networks in the recent past, wireless systems
are used every day and everywhere.
Wireless Home Automation system (WHAS) using IoT is a system that uses computers or mobile
devices to control basic home functions and features automatically through internet from anywhere around
the world, an automated home is sometimes called a smart home. It is meant to save the electric power and
human energy. The home automation system differs from other system by allowing the user to operate the
system from anywhere around the world through internet connection.

4. WHAT IS IoT?
• The Internet of Things is simply "A network of Internet connected objects able to collect and exchange data." It is
commonly abbreviated as IoT.
• The word "Internet of Things" has two main parts; Internet being the backbone of connectivity, and Things meaning
objects / devices .
• In a simple way to put it, You have "things" that sense and collect data and send it to the internet. This data can be
accessible by other "things" too.
• Let me give you a practical example. Lets imagine you have a "Smart air conditioning unit" in your home that is
connected to the internet. (This is a "thing" connected to the internet) Now, imagine it's a hot summer day and you
have left for home from your work. You would like your home to be cool enough by the time you enter it. So, When
you leave from your office, you can remotely switch ON the air conditioning unit of your home using your mobile
(another "Thing" connected to the internet). Technically, with internet, you can control your AC system from any part
of the world as long as both the AC and your mobile are connected using the "Internet".

5. AUTOMATION
Automation is, unsurprisingly, one of the two main characteristics of home automation. Automation refers to
the ability to program and schedule events for the devices on the network. The programming may include
time-related commands, such as having your lights turn on or off at specific times each day. It can also include
non-scheduled events, such as turning on all the lights in your home when your security system alarm is
triggered.
Once you start to understand the possibilities of home automation scheduling, you can come up with any
number of useful and creative solutions to make your life better. Is that west-facing window letting in too much
light? Plug your motorized blinds into a “smart” outlet and program it to close at noon each day. Do you have
someone come by at the same time each day to walk the dog? Program your home automation system to
unlock the front door for them, and lock it up again when they’re done.

6. HOME AUTOMATION SYSTEM
• Home automation involves introducing a degree of computerized or automatic control to certain electrical
and electronics system in a building.
• These lighting, temperature control, etc.., this project demonstrates a simple home automation system which
contains a remote mobile host controller and several client module (home appliances).
• The client modules communicate with host controllers through a wireless device such as a Bluetooth
enabled mobile phone, in this case, an android based smart phone.
Our proposed system DGHOME is a building automation device for a home, called a smart home or smart
house. A home automation system will control lighting, climate, entertainment systems, and appliances. It may
also include home security such as access control and alarm systems. When connected with the Internet, home
devices are an important constituent of the Internet of Things.

10. WORKING PRINCIPLE
The proposed system "DGHOME" is a distributed home automation system, consists of server,
sensors. Server controls and monitors the various sensors, and can be easily configured to
handle more hardware interface module.
The NodeMCU is an efficient and perfect size to fit in our everyday use device. If the
sensor parameters are greater than the threshold level then the respective measures can be
taken through internet like 'switch off a light' or 'raising up an alarm' etc. The required lights are
turned on/off automatically by detecting the light outside the house. The user can also monitor
the electric appliances through the internet via web server.

11. A home automation system typically connects controlled devices to a central hub or "gateway". The user
interface for control of the system uses either wall-mounted terminals, tablet or desktop computers, a mobile
phone application, or a Web interface, that may also be accessible off-site through the Internet.
There are three main elements of a home automation system: sensors, controllers, and actuators.
• Sensors can monitor changes in daylight, temperature, or motion detection. Home automation systems can
then adjust those settings (and more) to your preferences.
• Controllers refer to the devices — personal computers, tablets or smartphones — used to send and receive
messages about the status of automated features in your home.
• Actuators may be light switches, motors, or motorized valves that control the actual mechanism, or function, of
a home automation system. They are programmed to be activated by a remote command from a controller.

21. ADVANTAGES
The purpose of a home automation system is to streamline how your home functions. Consider some of these
benefits:
•Remote access: Control your home from mobile devices, including your laptop, tablet, or smartphone.
•Comfort: Use home automation to make your home a more comfortable, livable space. Pre program your
thermostat with your preferred settings so that your home is always at a comfortable temperature, set up smart
speakers to play music when you get home from work, or adjust your lights to soften or brighten based on the
time of day.
•Convenience: Program devices to turn on automatically at certain times, or access their settings remotely from
anywhere with an Internet connection. When you don’t have to remember to lock the door behind you or
switch off the lights, you can turn your attention to more important things.
18

22. •Increased safety: Smart fire detectors, carbon monoxide monitors, pressure sensors, and other
home automation security features can help protect your home from disaster.
•Energy efficiency: Home automation allows you to be more mindful of your power usage. For
example, you can save on energy bills by reducing the length of time that lights stay on, or by
lowering temperatures when you leave a room.

23. DISADVANTAGES
In a review of home automation devices, Consumer Reports found two main concerns for consumers:
•A Wi-Fi network connected to the internet can be vulnerable to hacking.
•Technology is still in its infancy, and consumers could invest in a system that becomes abandonware. In
2014, Google bought the company selling the Revolv Hub home automation system, integrated it
with Nest and in 2016 shut down the servers Revolv Hub depended on, rendering the hardware useless.
•Microsoft Research found in 2011, that home automation could involve high cost of ownership, inflexibility of
interconnected devices, and poor manageability.

24. CONCLUSION
Home Automation is undeniably a resource which can make a home environment automated. People can
control their electrical devices via these Home Automation devices and set up controlling actions through Mobile. A
home control system controls the user’s whole house, triggering routines and events involving Home Subsystems. An
automation system controls a collection of “Home Subsystems”.
There is a need for a reliable, secure and interactive system that exercises full control over the electric and electronic
aspects of the house, with the potential to be accessed from across the globe.
The Smart House system would adjust the power supplied to each appliance according to need. Each
appliance is provided with sufficient power to provide for its peak use. In addition, the Smart House controllers could
schedule the operation of heavy power consuming appliances (such as dishwashers, electric water heaters, and air
conditioners) to take maximum advantage of off-peak electric rates. These adjustments could result in lower utility
costs.
