    RFID and IR Based Attendance System RFID and IR Based Attendance System Presentation Transcript

    • RFID AND IR BASEDATTENDANCE SYSTEM
    • Aim and objectives of Project.Block diagram.Circuit diagram of RFID.Working of CircuitApplications of RFID.Result and Conclusion.Future ScopeAcknowledgementOverview of Presentation
    •  To understand the Microcontroller and itsapplication. 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.
    •  Basic system components(tags, readers & middle ware) Tags consists of a microchipattached to an antenna and isplaced in the object to belocated. Various types oftags…passive, active Reader communicates with thetags through radio waves. Staffwork stations, handheldreaders, self-chargingstations, long range exit readersystems Middleware converts the datacaptured by the reader into aformat that is perceivable bythe application software6/11/2013RapidRadio Solutions Pvt. Ltd. 5Tag
    •  The RFID Reader Module is controlled with asingle TTL-level active-low /ENABLE pin. Whenthe /ENABLE pin is pulled LOW, the module willenter its active state and enable the antenna tointerrogate for tags. A visual indication of the state of the RFIDReader Module is given with the on-board LED. When the module is successfully powered-upand is in an idle state, the LED will be GREEN. When the module is in an active state and theantenna is transmitting, the LED will be RED.Here comes your footer  Page 6

Infrared waves areinvisible to human eyes. Thewavelength region of 0.75µm to 3 µmis called near infrared, the regionfrom 3 µm to 6 µm is called midinfrared and the region higher than 6µm is called far infrared.

RFID and IR pair is interface to themicrocontroller and LCD is interface to show the cardnumber.IR detects the pulse when human enters the swappingarea and this information is shown on LCD When RFID tagis swap on the reader, it detects the tagnumber, simultaneously.When a student enter the IR pair detect person’s countand the IR signal will be high that signal will send tomicrocontroller after the IR signal become high thenonly RFID tag can swap .If IR pair does not detect a person then RFID Tag willnot read

    •  The RFID and IR based attendance systemusing microcontroller NXP 89V51” issuccessfully completed, designed, simulated,build and tested. We have successfully completed, designed,simulated, build and tested.
    •  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 tagfrom far distance. RF TRANSRECEIVER module can be used for long distancecommunication to transfer data. The transferred data can be save and store in computer as a database usingspecific software. Timely attendance can be monitored i.e. time in and time out can berecorded using RTC (real time clock) and can be stored in the database. This attendance system’s data base can be linked with college website andcan be shared and monitored by the student’s parents.
