3.  Now a days 99% of the board examination are held jumbling system. In this process
so many students facing problems in searching rooms. Most of the students feel tense
before coming to exam and they still feel tense in searching for their place for exam.
PROBLEM STATEMENT
Dept of ECE, Maharaja Institute of Technology Thandavapura

4. ABSTRACT
Most of the board exams conducted in manual ways. It is a very difficult task to conduct the exam for large
number of students. The information communications techniques are used in various fields. Communications
technologies are used in educations institutions also for storing student data, faculties’ data, execute the exams
etc. Now the exam seating setup was created and uploaded on the internet. The students gave the register
number as the input and collect their exam location. It was a very difficult and time consuming task. To avoid this
problem a new system is proposed RFID technology. It is the new method for exam location management. Using
this system the students are able to identify their exam location easily and avoid unauthorized person to enter
inside the exam hall.

• Pin(1) ANT is used to connect the antenna.
• Pin(2) VCC is used to connect the VCC.
• Pin(3) RST is used to reset the module.
• Pin(4) RXD is used as a receiver pin.
• Pin(5) TXD is used as a transmitter pin.
• Pin(6) GND is used to connect GND.
• Pin(7) Ring outputs logic LOW while receiving calls.
• Pin(8) DTR is used for sleep mode.

14. SIM800L Network Status LED Indication:
• The SIM800L module has a network status indicator LED which blinks at different rates to indicate the network
state.
• Blink at every 1sec suggests that the chip is running but hasn’t made a connection to cellular network yet.
• Blink at every 2sec suggests that GPRS data connection that user requested is active.
• Blink at every 3sec suggests that module has made contact with cellular network and which can send/receive
voice and SMS

15. RFID Tag: (RFID-Radio Frequency Identification)
 RFID tag is a small device which stores and sends data to RFID reader .
RFID tags are made out of three pieces:
 A micro chip : an integrated circuit which stores and processes information and modulates and demodulates radio-
frequency (RF) signals.
 An antenna : for receiving and transmitting the signal.
 Substrate : The tag information is stored in a non-volatile memory.The RFID tag includes either fixed or
programmable logic for processing the transmission and sensor data, respectively.
• They are categorized in two types :
1) Active tag:
• Active tags are those which contain an internal battery and do not require power from the reader .
• Active tags have a longer distance range than passive tags.
Dept of ECE, Maharaja Institute of Technology Thandavapura

16. 2) Passive tag
• Passive tags are smaller and lighter in size than the active tags.
• They do not contain an internal battery and thus depend on RFID reader for operating power and certainly
have a low range limited up too few meters.

17. RFID Reader:(RC522)
• Which is also referred as Radio-Frequency Identification
• RFID scanner uses electromagnetic waves.
• To transmit these waves ,the scanner uses an antenna that transmits a signal, communicating
with the tags antenna.
• The tags antenna receives data from the scanner and transmits its particular chip information
to the scanner.
• The data on the chip is usually stored in one of two types of memory.
1)Read-Only Memory (ROM)
2)Read/Write Memory
