PD0 and PD1 pins of microcontroller.VCC is connected to 5v and GND is connected to ground. These pins are connected to the transmit and receive pins of the micro controller i.e. The RFID Reader has transmit and receive pins. RFID based attendance system has very simple circuit design. Circuit 1 RFID Based Attendance System Circuit Diagram using AVR Circuit Diagram of RFID Based Attendance System – Electronics Hub Circuit ComponentsĬircuit Design of RFID Based Attendance System Also you can check out the rfid based attendance system output video. If the tag is authenticated, microcontroller takes the attendance. Microcontroller checks for the data continuously, if any data is received, microcontroller compares the data in data base. Reader then transfers data to the microntroller. When the tag is placed near the reader, due to the induced mutual inductance energy, data is transferred to reader. RFID reader contains a copper winding in it.

In real time, one can issue active tags to the students, with their roll numbers as their tags. one can read from the tag and write to the tag. Passive tags contain 13 digit number tag inbuilt in it, where as active tag is read/write tag i.e. RFID tags are of two types – 1) Passive Tags and 2) Active Tags. Radio frequency technology is used in many applications. Data is transferred from RFID cards to reader and from there to microcontroller. RFID can be interfaced to microcontroller through USART. RFID based attendance system consists of RFID Reader, RFID Tag, LCD display and microcontroller unit.

Operating voltage of EM-18: +4.5 V to +5.DIY Project Kit : RFID based Attendance System » RFID Based Attendance System Circuit Principle.

If the baud rate mismatches you will get some garbage output on your terminal. The default baud rate of this module is set to 9600 bps (bits per second), Use the same baud rate to retrieve information. I am going to use RS232 here because of its popularity.

If the SEL pin is set to HIGH the communication medium will be RS232 (UART) and if the SEL pin is pulled down to LOW the communication medium will be WEIGAND. It can be selected by setting the logic output on the SEL pin of EM-18. EM-18 RFID Reader can provide output via two communication methods "RS232" and "WEIGAND". As you know RFID Library for Proteus is not available yet, so I found a way to simulate it using a virtual terminal.īefore Starting, I will share some details about the EM18 RFID Reader based on UART Communication. Hello Guys, In this simulation tutorial, I will help you to simulate an RFID reader in Proteus with Arduino UNO.
