Abstract - Home automation is an important milestone in
achieving smart grid technology. Advancement in
technologies have made homes appliances to be monitored
and controlled more efficiently and securely.Introduction of
Raspberry Pi to the world of home automation allows
numerous customizations to turn a regular home into a
smart home.
Raspberry Pi provides a low cost platform for
interconnecting electrical/electronic devices and various
sensors in a home via the internet network.
This paper highlights the design and implementation of
Smart Home automation system with surveillance
monitoring system using Raspberry pi and PIR sensor for
mobile devices. It increases the usage of mobile technology
to provide essential security to our homes and for other
control applications.
Key Words: Raspberry Pi, PIR sensor
1. INTRODUCTION
This project focuses on helping users to operate home
appliances with their own smartphones and to help to live a
more independent life as long as possible. The motto of
designing our system is to take care of several domestic
appliances to be monitored and controlled. The proposed
design will allow a user to download software on their
android enabled smart phones and monitor and control the
applications and devices as required. This application will
allow the user to control a device that is connected to any
home appliance that is Pi enabled. The focus of this
application will be to direct a security system with webcam
surveillance, door sensor notification and a light control
system. Sensors like LPG, smoke detector will be connected
to the home appliances with Pi sothattheycanbe monitored
and controlled.
The proposed system would enable the client to monitor his
home when a door or a window sensor triggers the alarm.
Client monitors his home with webcam and could
immediately inform local authority or a policeman. The
Client could also check the status of the outside light and
turn on and off the light without the need to get out of bed.
These devices would also benefit users withlimitedmobility
that may have a difficult time getting to or even reaching
their light switch. These objectives requirea largeamount of
technology. The user interface must be as simple and
powerful as possible and operate in a self _organized way.
1.1 Literature review
Currently, there are many papers on home automation
systems already published by different authors that provide
similar functionality on a smaller scale.
For example, in
[1.] “Smart Home Control by using Raspberry Pi & Arduino
UNO”, the system utilizes network based Raspberry Pi2 and
Arduino Uno Microcontroller with an aim to provide
flexibility and to lower the cost to the smart home
automation process. However, this system requires many
components, which adds to its complexity and cost
[2]. One of the systems in “Internet of Things based Home
Automation using Raspberry PI” describes the use of
Internet of Things (IoT) concept to interface home
appliances with each other using Raspberry Pi. This system,
however, uses a web-based interface, which lacks. The ease-
of-access for its user
[3]. Another unpopular system in “Home automation using
Raspberry Pi” suggests making the use of an older version of
Raspberry Pi, which does not contain inbuilt Wi-Fi support
[4].This increases the costs significantly, whilst also
increasing complexity of the circuit.
However, our proposed system not only aims to be smart
and efficient, but also simple, cost-effective and
technologically up-to-date.
1.2 Objective
The objective of our system is to take care of several
domestic systems that may normally be difficult. The
proposed idea will allow a user with any android enabled
device to run a piece of downloadable software on any
mobile device such as a smartphones. This application
allows the user to control a device that is connected to any
home appliance that is Pi enabled. The focus of this
application is to direct a security system with webcam
surveillance, door sensor notification and a light control
system. Sensors are connected to the home appliances with
Pi so that they can be monitored and controlled.
2. Functional Block Diagram
A.USB Camera captures the image and sends it to the USB
port of the Raspberry Pi board. The camera model usedhere
is USB Camera model 2.0.

B. Raspberry Pi: Raspberry pi is a small credit-card sized
computer capable of performingvariousfunctionalities such
as in surveillance systems
C. A PIR motion sensor consists of a Fresnel lens,aninfrared
detector and supporting detection circuitry. The lens on the
sensor focuses any infrared radiation present around it
towards the infrared detector. Our bodies generate infrared
heat and as a result this gets picked up by the motion sensor
D. L293 contains two inbuilt H-bridge driver circuits. In its
common mode of operation, two DC motors can be driven
simultaneously, both in forward and reverse direction. The
motor operations of two motors can be controlled by input
logic at pins 2 & 7 and 10 & 15. Input logic 00 or 11 will stop
the corresponding motor. Logic 01 and 10 will rotate it in
clockwise and anticlockwise directions, respectively

2.1 Results
Mentioned below are the test results which indicates the
successful achievement of smart home automation system
When the switch of a device connected to raspberry PI is
switched on at the web application that can be operated via
smart phone or laptop as shown in the fig a the relay light
glows indicating that the device is turned on remotely via
web based application. Fig b shows the relay light being
turned on as soon as the switch for device is turned on
Fig a
Fig b
Fig c indicates that when a match stick is ignited in front of
the flame sensor. Thus the sensed parameter output is
displayed on the web application as shown in fig d
Fig c
Fig d
Fig e indicates that when a motion is detected by the PIR
sensor the web cam captures the image of a person and
sends it to the web application indicating that the motion is
detected

3. CONCLUSIONS
Thus we have designed a smart surveillancesystemcapable
of recording/capturing video/image and transmitting to a
smart phone whenever a motion is detected byPIR sensor.It
is advantageous as it offers reliability and privacy. It is
authenticated and encrypted onthereceiverside; henceonly
concerned person who is monitoring would be able to look
into the details when logged in the web application.
The person who is monitoring the home from the remote
area would be able to monitor the opening and closingofthe
door on the application accessed remotely
Smart on/off feature for the devices are enabled on this
application web page to monitor and control the devices
connected.
Detection of fire and LPG leakage is achieved and is notified
on the application web page.
