This document describes an RFID and IR based attendance system project. It includes the aim, block diagram, circuit diagram of RFID, working of the circuit, applications of RFID, and results and conclusions from developing and testing the system. An RFID reader module controlled by a microcontroller reads RFID tags when an IR sensor first detects a person's presence. The system allows for automated attendance tracking to reduce paper records and store data longer term. Future scopes involve enhancing the range and data transfer capabilities.

- 1. RFID AND IR BASED ATTENDANCE SYSTEM
- 2. Aim and objectives of Project. Block diagram. Circuit diagram of RFID. Working of Circuit Applications of RFID. Result and Conclusion. Future Scope Acknowledgement Overview of Presentation
- 3. To understand the Microcontroller and its application. To understand the working of RFID module. To understand the working of IR sensor. Build a Interfacing circuit with RFID and IR. Develop basic programming architectures.
- 5. Basic system components (tags, readers & middle ware) Tags consists of a microchip attached to an antenna and is placed in the object to be located. Various types of tags…passive, active Reader communicates with the tags through radio waves. Staff work stations, handheld readers, self-charging stations, long range exit reader systems Middleware converts the data captured by the reader into a format that is perceivable by the application software 6/11/2013RapidRadio Solutions Pvt. Ltd. 5 Tag
- 6. The RFID Reader Module is controlled with a single TTL-level active-low /ENABLE pin. When the /ENABLE pin is pulled LOW, the module will enter its active state and enable the antenna to interrogate for tags. A visual indication of the state of the RFID Reader Module is given with the on-board LED. When the module is successfully powered-up and is in an idle state, the LED will be GREEN. When the module is in an active state and the antenna is transmitting, the LED will be RED. Here comes your footer Page 6

Here comes your footer Page 8 Infrared radiation is the portion of electromagnetic spectrum having wavelengths longer than visible light wavelengths, but smaller than microwaves, i.e., the region roughly from 0.75µm to 1000 µm is the infrared region. Infrared waves are invisible to human eyes. The wavelength region of 0.75µm to 3 µm is called near infrared, the region from 3 µm to 6 µm is called mid infrared and the region higher than 6 µm is called far infrared.

RFID and IR pair is interface to the microcontroller and LCD is interface to show the card number. IR detects the pulse when human enters the swapping area and this information is shown on LCD When RFID tag is swap on the reader, it detects the tag number, simultaneously. When a student enter the IR pair detect person’s count and the IR signal will be high that signal will send to microcontroller after the IR signal become high then only RFID tag can swap . If IR pair does not detect a person then RFID Tag will not read

- 12. The RFID and IR based attendance system using microcontroller NXP 89V51” is successfully completed, designed, simulated, build and tested. We have successfully completed, designed, simulated, build and tested.
- 13. The project can be developed using advanced microcontroller like ARM 7, ARM 9 etc. Range of the RFID reader can be increased, so the reader can detect the tag from far distance. RF TRANSRECEIVER module can be used for long distance communication to transfer data. The transferred data can be save and store in computer as a database using specific software. Timely attendance can be monitored i.e. time in and time out can be recorded using RTC (real time clock) and can be stored in the database. This attendance system’s data base can be linked with college website and can be shared and monitored by the student’s parents.
