4. Introduction
 The quality of education is a vital demand in today's competitive
setting. Technology has affected us in each facet.
 Smart Education situation in India that offer quality teaching and
learning opportunities to lecturers and students by serving them
to longer devotion towards the teaching, better construct
formation and educational action.
 Smart room provides energy efficient room automation by
controlling, monitoring and utilization of renewable energy
sources while reducing operating cost of appliances.

5.  SMART CLASS ROOM automation mainly focuses on Controlling and
monitoring of lights, fan, AC and other room appliances by considering
workable and human friendly room environment.
 IoT (Internet of Things) is inter-networking of physical devices,
embedded systems, buildings, sensors, actuators and other similar
devices to stay connected and exchange data.
 Simplify the task of attendance recording by the use of the Q-touch
sensors and also using RFID technology to ensure strictness among the
students.
 Wire-less electronic notice board to convey information from the faculty
and the student.

6. Background
 IOT enabled and embedded Smart classrooms have been a
product of development and adoption of technology in the
education sector.
 With advancement of technology such as streaming of video on
the web, the need to have a classroom as a meeting point is no
more
 Smart classroom technologies have enabled listening of lectures
from any place. Recording of what transpires in a lecture room
has also avoided the problem of having to obtain the information
together with the rest of the students as one can always listen at a
convenient time and as many times as possible.

7.  Smart classrooms have been successful due to the availability of aspects of
interactive communication and collaboration instruments such as chat
rooms, electronic forums like teleconferencing, and e-mail applications
among others.

8. OBJECTIVES
 To create advancement in education systems.
 To build a prototype for smart classroom controlled by using Raspberry
Pi, RFID sensors, WAGO PLC controllers along with relays.
 To make a better learning and understanding.
 Students learn their lessons in a smart approach.
 Solar supply for the projector, lights, fans, helps in the time of power
cuts.
 Helps to keep track of students.

9. A smart classroom is where the concept of
blended learning is blooming. The smart
classroom is technologically enhanced that
enables teaching and learning opportunities like
never before!

10.  Smart classrooms are the classrooms enhanced with
technological equipment for the purpose of better learning
and teaching.

12.  Smart class technology allows students to make presentations online
and get feedback from their teachers in less time. This saves a lot of time
of teachers and students that can be used for another interactive activity.
 The opportunity to provide students with quality education by helping
them understand concepts better, improve their reading and
comprehension skills, and achieve academic excellence.
 It is a universal truth, when we learn through visuals, we grab the
subject easily rather than just looking into the blackboard & listening.

14.  The education sector has seen a noticeable increase in educational standards,
advancement and innovations in recent years.
 Schools and other educational institutions have begun to adopt modern
teaching methods through interactive intelligent boards, projectors and smart
notebooks, etc.
 we can not deny, these technological updates make the education system more
interactive and easier.
 Students prefer to use tablets, phones and other devices to share and transfer
study material that saves their time and efforts.
 On the other hand, this smart technology helps teachers to turn boring lectures
into an engaging session. It is not just about sharing information but also
creating a better online presentation by avoiding the need to write manually.

15.  Smart Technology use by teachers in classrooms

16.  Survey findings revealed that teachers reported integrating technology
into the classroom (74%)

(IOT) Internet of Things
 Internet of Things (IOT) is the organize of "things" or objects
coordinates in electronics, software, sensors and organize network,
which permits these things to gather and replace a huge sum of
information.

22. IOT APPLICATIONS FOR SMART CLASSES
 Environmental monitoring or infrastructure management or labor
process.
 For data transfers.

26.  Present Classroom Modifications

27.  The Q-touch sensors are placed on the chairs. These devices are
charging a sense electrode of unknown capacitance to a known
potential.
 When we place a finger on the touch surface it introduces external
capacitance which affects the charge flowing at that point this is
registered as a touch.
 Q-touch microcontrollers can also be used to detect the proximity
of a finger, rather than an absolute touch.
Q-Touch Sensor

28.  Q-Touch technology is basically deployed in two ways, normal mode or
touch mode and high-sensitivity or proximity mode.
 The high sensitive charge transfer proximity sensing. It is used for
detecting an end-user's approaching finger, and the user interface interrupt
the electronic equipment.

29. Microcontroller (SAMD21)
 Atmel SMART SAM D21 is a series of low-power microcontrollers that
uses the 32-bit ARM Cortex -M0+ processor. Pin ranges from 32 to 64
pins with 256KB Flash and 32KB of SRAM. SAM D21 .
 devices operate at a maximum frequency of 48MHz and can reach up to
2.46 Core Mark/MHz.

30. RFID Technology
 RFID stands for Radio frequency identification which makes use of
electromagnetic fields to automatically identify and track tags which are
attached to objects.
 In case of passive tags it collects energy from a nearby RFID reader's
interrogating radio waves.
 Unlike a barcode, it’s not necessary tag need not be within the line of
sight of the reader, so it can be embedded in the tracked object.
 RFID is one of the bestmethod for Automatic Identification and Data
Capture (AIDC).

31.  The student cards being used for identification of each individual student are
the RFID cards consist of passive RFID tag, which does not require internal
battery.
 Now these cards are passed through the field generated by a compatible
reader and it transmit information back to the reader.
 RFID tag and reader

32. RECOGNISED PROBLEM STATEMENT AND SOLUTION
Having said the limitations imposed by the conventional attendance
system,
 A solution in the form of Q-touch sensors which will be placed in the
respective chair of a particular student.
 The main idea behind the system is to capture student attendance in a
automated way where the students are required to flash their student
card at the RFID reader to get access inside the classroom and take
their respective seats.
 The time period will be calculated for the amount of time they are
seated in their seats and graph will be plotted accordingly. This data
will be saved and sent to the attendance department through the main
server.
