Biometric Sensor Using Arduino

Every key has double features.

Biometric sensor using arduino.

Enroll key is used for enrolling new finger impression into the system and back function as well. The type of fingerprint module we are using is the r305 fingerprint scanner module. In this project we are going to design fingerprint sensor based biometric attendance system using arduino. Here we are using 4 push buttons to register new fingerprint or delete stored fingerprint or match stored fingerprint.

Fingerprint sensor module captures finger s print image and then converts it into the equivalent template and saves them into its memory as per selected id by arduino. In this fingerprint sensor based biometric attendance system using arduino we used a fingerprint sensor module to authenticate a true person or employee by taking their finger input in the system. Here we are using 4 push buttons to enroll back delete ok up and down. This sensor has an optical heart rate sensor with amplification and circuit for noise reduction giving fast and reliable pulse readings.

In this project we will be interfacing fingerprint sensor with arduino for biometric security system. To measure the heart rate you just need to clip the sensor in your earlobe or fingerprint. Simply we will be interfacing fingerprint sensor w. Security is a major concern in our day to day life and digital locks have become an important part of these security systems.
