Smart home system is very popular in current days that give many kind of application
that make all simple and easy to control. When it comes to our house this concept can
be apply incorporated to make it smarter, safer and automated. Considering the fact of
increasing demand of home security and automation, an IoT based control system is
presented in this paper where the proposed system can maintain the security of home
main entrance. IoT based Home Computerization System is designed to assist the
people with physical debilities and elderly to provide support as well as to control the
electrical usages and monitor the room infection using IoT application. The design is
using surrounded controller board and the home appliances are physically associated to
output ports of this board via relays. The Home Automation is a wireless home
computerization system that is supposed to be executed in existing home environments,
without any variations in the infrastructure. The hardware part is designed with the
Arduino microcontroller.

5. Introduction
??Smart security mechanization is very popular due to its many benefits in capable area,
these techniques will controls all the automated devices which will reduce the human
envelopment to get reduce. It will provide various assistances such as greater safety,
comfort, and security, a more rational use of energy and other resources thus underwriting
to a important savings. The theory of home automation has been around since 1970‟s.As
much as IoT helping in automating tasks, the benefits of IoT can be extended for build up
the current safety standards. The modern homes are automated through the internet and
the home appliances are controlled. This challenges make smart homes extremely
vulnerable to different types of security attacks, resulting in IoT based smart homes being
insecure. In this project by using Internet of Things (IoT) we will control the home
appliances.

6. Objective
• To developed the home security, safety and home
automation system.
• To Detect the Unknown person vary firstly and the
authorities can be informed quickly through the
GSM module.
• To detect the over temperature, harmful gas, fire
and gas leakage through the different sensor.
• To developed the energy saving system by motion
sensor.
• To develop the IoT system for monitoring the
home appliances.

 We added the different types Sensor.
 We developed the security system of very low cost.
 We developed the energy saving system.
 We show the all sensor value at the server .
 We send the specific notification of home present
condition at server and authorities Mobile phone .

12. Advantages
• Accessing information is easy, we can control a device that
is miles apart in real time.
• Automation is the need of the hour; IoT reduces human
intervention and increases efficiency of services.
• Easy of installation and the system is designed in user
friendly interface.
• Better scalability and flexibility.
• It can also improve safety and remove risk of human error.
• The main advantages is to help for physically challenged
and disabled people.
• Easy management of large data.

13. Advantages
• The project that we developed was intended for many future
applications in our country. These areas will be hugely
benefitted if they implement our system into their premises.
The major improvement that can be made on this system is the
end detector. Instead of using just flame detectors we can use
Thermo-graphic cameras.
• We can also use PUC machine instead of MQ2 gas sensor LPG
gas leak or methane gas leak. The controlling unit can be
replaced with a Raspberry Pi 3 which is more than 40 times
faster than an Arduino Nano.
• All in all, our system can be of great value to the industry
owner as they can implement this in their designated places and
provide safety and security to the general public of our country.

14. Conclusion
• IoT communications and information technology, with the objective to
improve reliability, operating efficiency and reduce impact to the
environment. The home automation system has been experimentally proved
to work satisfactorily by connecting sample appliances to it and the
appliances were successfully controlled from a wireless communication
system. Home security is rapidly growing field and there are news and
improved burglar alarms popping up every day. People can control their
electrical devices through set up controlling actions through sensor based
energy saving system. Finally we come to a conclusion that before making
the decision of installing home security system we must gather complete
knowledge about the security system. The hardest work was interfacing the
mobile hotspot to system wifi module connected, arduino to sensor value,
shown the sensor value at server and LCD display etc. Our system has been
better monitoring using sensor networks and communications, better and
faster balancing of supply and demand, improving power Reliability and
Quality. If we make more of that system then our project development cost
will be reduced. We try to great motivation and effort, final successful
implementation of the project has become possible. 14
