Module checks these two images and generates a template image and stores it. Initially, to enroll the finger user must give his finger print twice to the module.

Data can be transmitted or received using serial communication.įinger print processing involves two steps.1) finger enrollment and 2) finger matching. Vin is applied with a voltage of 5V and GND is connected to ground. Receive pin should be connected to the transmit pin of the microcontroller. Transmit pin is connected to the receive pin of the microcontroller. This module has four pins out 1) Transmit, 2) Receive, 3) Vin, 4) GND. USART is universal synchronous and asynchronous receiver and transmitter. Here, USART protocol is used for communicating with the micro controller. It supports USART communication protocol. It has 8 KB of flash memory, 512 bytes of EEPROM, 1KB of SRAM.īiometric module used here is R305 series finger print module. It is 8 bit microcontroller and has 23 programmable input and output pins. Here, we used an ATmega8 microcontroller which is an AVR family microcontroller.

Microcontroller receives these commands from the finger print module and uses the internal EEPROM to store the attendance. This sends commands to the controller when ever finger print is matched. Main heart of the circuit is finger print module. Inside the finger print module a DSP processor is present to implement and analyze the algorithm. When the finger print is given it stores the points where there are changes in the direction of ridges and valleys using some algorithms.

Finger print module differentiates between two fingers based on the ridges and valleys on finger print.

This is because of the peculiar genetic code of DNA in each person. The main aim of this circuit is to take the attendance and display when requested.įinger print identification is based on the fact that no two persons will have the same finger print in this world.
