RFID Based Projects for Engineering Students

Radio-Frequency Identification (RFID) is a technology that uses radio-frequency electromagnetic fields to transfer information from an RFID tag to the RFID reader for identification purposes. The tags used do not require battery power and in turn, they derive power from the electromagnetic field generated from the reader. Few tags are also available which have their own power source. RFID technology is used in many industrial applications for tracking purposes. For example, it is used in manufacturing industries such automobile industry to track the vehicle during the complete production cycle of it. The RFID tags can also be fixed to books, mobile phones, electronic equipment for tracking purposes. This article discusses RFID based projects for engineering students.

RFID Based Projects for Engineering Students

The radio-frequency is an automatic identification process used for transmitting data between an RFID tag and RFID reader with the help of radio-frequency electromagnetic fields. The RFID tag is a device used to store data of any stuff, persons, books, animals, etc.  RFID tags are of different types some tags can be placed near to the RFID reader and some can read from far away distances beyond the line of sight of the reader.


RFID Applications
RFID Applications

There are different types of RFID systems in the market that consists of an antenna, transceiver, and a transponder. These systems operate at different frequency ranges like low frequency (30-500 kHz), mid-frequency (900-1500 kHz), and high frequency (2.4-2.5GHz). Let us see one of the example-based applications of the RFID-based-attendance-management system in brief.

Below mentioned are few RFID based projects ideas that will help engineering students to understand RFID technology and to develop various applications out of it. These RFID based projects can be used for multiple applications by just modifying the program burnt in the microcontroller.

RFID Security Access Control System

The RFID system is used to authorize the tag holder to enter a secure area. It reads the data present on the RFID tag and compares it with data present in the microcontroller. If the data is matched, it displays the status of authorizing the entry which is indicated with a lamp coupled with an LCD display. 

Here the RFID card is used, which is inductively coupled to the reader. When the card is swiped against the reader, the modulated data from the card is sent to the reader. This data is fed to the microcontroller.  The card used is the identity card for the particular person and carries his/her details. When this data matches the data stored in the database of the microcontroller, the person is given the authority to enter the secured area. Here this is indicated by the lamp is switched on.

PCBWay

The microcontroller is programmed such that when the data matches with the existing data, the relay driver gets a high logic input at one of its input pins. The corresponding output pin goes low to provide a proper connection to the relay. The relay coil now gets energized and the armature shifts its position such that now the whole circuit is completed and the load gets supply from AC mains and gets switched on. The status of the authority of the person is also displayed on the LCD display interfaced to the microcontroller.

RFID based Attendance System

An RFID tag is used along with the reader to input the details of the employee/ student for tracking their attendance. When the RFID is swiped on the reader, the data of the tag is compared with data in the microcontroller (interfaced to the reader) to identify the user. An LCD is interfaced to the microcontroller to display the name of the user. Additionally, a status button is used to display the overall attendance of the user.

Here an RFID tag is used which is indirectly connected to the RFID reader using the inductive coupling method. As the tag or the card is swiped against the reader, the tag receives a carrier signal from the reader and in turn modulates the carrier signal and sends it back. The reader receives this modulated signal and sends this data to the microcontroller. The microcontroller compares this data with the existing data and on pressing the status push button, the status of the cardholder is shown on the display, indicating the attendance of the cardholder.

RFID based School Attendance System

The aim of this project is to maintain the record of the students’ attendance by using RFID tags. Each student is issued with his/ her authorized tag, which can be used for swiping in front of the RFID reader to record their attendance.

In most of the colleges and schools, attendance is recorded manually – such a process consumes lots of time. In this proposed system, the attendance system is implemented by using advanced wireless technology “RFID”. Only the authorized students are provided with the RFID tags. This tag consists of an inbuilt integrated circuit for storing and processing information. The circuit diagram of the RFID based project for the school attendance system is shown below. The required components used in this project are discussed below.

Microcontroller

AT89C52 Microcontroller from 8051 families is used in this system. It consists of four ports and 40 pins.

Oscillator Circuit

The oscillator circuit is connected between the 18 and 19th pin of the microcontroller and consists of an oscillator with a frequency of 11.0592 MHz and two capacitors of 33pF.

Preset Circuit

The 9th pin of the microcontroller is the RST pin, which is the reset pin. This preset circuit comprises a switch, a capacitor of (10u), and a resistor of 10k. When the switch is pressed, the RST pin is connected to the power supply(Vcc) and the microcontroller gets reset.

LCD Display

The LCD display is used for displaying the data. It consists of 16 pins: three pins are connected to the power supply, and the remaining pins are connected to the port 2 of the microcontroller.

RFID Reader

The RFID reader is a module with an RFID reader and antennaIt is small in size and integrates with any sort of hardware design. It is used to read the data stored in the RFID tags.

Circuit Working

The data stored in this tag is referred to as the identification and attendance of the person. Once the student places the card in front of the RFID reader, it reads the data and compares the data stored in the microcontroller which is programmed by using Embedded C language.

If the data matches, then it displays the information on the LCD. This RFID attendance system also makes use of the status button for retrieving the status of students’ attendance, which is interfaced to the microcontroller. By using this advanced concept, a lot of time can be saved as all the students’ attendance information is directly stored in the database.

Device Control and Authentication

The RFID tag consists of an integrated circuit,  which is used for storing and processing the data, modulating and demodulating the radio frequency signal that is to be transmitted. When a person shows the RFID tag in front of the RFID reader and the reader reads the data and compares the data stored in the system.

If the data matches the stored data, the system authorizes the person and allows them to enter into the secured area so that the person can take control of various devices. The system also displays the result on the LCD. If it finds the provided information mismatched then, it alerts an unauthorized entry with a buzzer sounds as an indication of entering or providing wrong information.
