ABSTRACT
 This project aims to reduce the paper usage in the name of sticking notices in
conventional notice board.
 LCD display is used as an electronic notice board for displaying message sent
through SMS or by WEB APPLICATION.
 For secured usage of notice board, the password should get matched with the
predefined password.
 First, the user has to send the message to GSM module which will get displayed
on the LCD.
 Then the raspberry pi will send the displayed message to some mobile numbers
which were already stored.
 In web application images can also be sent.

INTRODUCTION
 Notice Board is a primary thing in any institution/organization or
public utility places.
 Sticking various notices day-to-day is a difficult process. A separate
person is required to take care of this notices display.
 A permanent solution for these difficulties is wireless access to the
Notice board, with a user friendly system.
 Hence, this project is built around raspberry pi which provides all
the functionality of the display and wireless control.

DISADVANTAGES OF EXISTING SYSTEM
 Coverage area of Bluetooth or zigbee is small.
 So the user want to be in a particular limit.
 Difficult to send text through Bluetooth.
 Unauthorized users can also able to send the message.

Why Raspberry pi?
 Raspberry pi 3 model consist of 64-bit quad-core ARM Cortex-A53 processor.
 Open source technology.
 It is having HDMI male cable connection option so LCD monitors can easily get
connected.
 It has in built wi-fi and Bluetooth module, which will support future
advancement.
 Program memory(RAM) size is 512MB.
 Processor speed ranges from 700 MHz to 1.2 GHz.
 It is having additional SDcard (secure digital card).

AUTHENTICATION
 To display the required notice in raspberry pi connected LCD
display the user has to send the notice or message along with the
password.
 The password has been already programmed to Raspberry pi if the
password matches, then the notice will get displayed.
 Otherwise, it will discard the notice.
 If we are sending notices via internet then the user have to log in to
the web application by using user id and password.

Advantages of GSM
 Using GSM mobile we can send message to any distant locations,
from any part of the World.
 GSM wireless transmission system it has very less errors and needs
less maintenance.
 It offers higher security to the transmitting data.
 Notifications can be delivered within second.
13/24

WEB APPLICATION
 We are using a web application named projectone.in/noticedisplay/
 The web application has been designed by using PHP.
 The displayed message/notice get stored in the web application.
 The notices can also get deleted through the web application.
 Notice can be a message as well as image can get displayed using
this web application.

ADVANTAGES OF PROPOSED SYSTEM
 No printing and photocopying costs.
 Thus saves time, energy and finally environment.
 Multiple Users are authorized to update notices on the electronic
notice board.
 Prevents unauthorized access of notice board.
 Problem related to direct manual update of notice board is removed.
Just an SMS is enough.
 Notifications can be delivered within seconds.
15/24

APPLICATIONS OF PROPOSED SYSTEM
 Educational institutions & organizations
 Bus/Railway station
 Conference hall
 Any Public utility places
16/24

OUTPUT
 First the required notice / message to be displayed is send to the
GSM number through SMS.
17/24

18/24 • After that the message get forwarded to authenticated user.

19/24
• For sending images the web application is used and the notices displayed in
notice board is also viewed in Web application

20/24
FINAL OUTPUT

CONCLUSION
 The idea of establishing IoT based smart board using raspberry pi 3
and GSM was successfully implemented.
 It is simple and secure way of displaying and forwarding notices and
it reduce manual effort & eco-Friendly.
 Since it using web application overall performance will improved.
