Biometric Sensor Using Arduino

The sensor can be easily powered up using the arduino 5v pin.

Biometric sensor using arduino.

Security is a major concern in our day to day life and digital locks have become an important part of these security systems. Here we are using 4 push buttons to enroll back delete ok up and down. In this arduino fingerprint sensor project we have used fingerprint sensor module to take finger or thumb impression as input in the system. Here we are using 4 push buttons to register new fingerprint or delete stored fingerprint or match stored fingerprint.

All the process is commanded by arduino like taking an image of finger s print convert it into templates and storing as id etc. The type of fingerprint module we are using is the r305 fingerprint scanner module. Every key has double features. In this project we will be interfacing fingerprint sensor with arduino for biometric security system.

Enroll key is used for enrolling new finger impression into the system and back function as well. In this project we are going to design fingerprint sensor based biometric attendance system using arduino. To measure the heart rate you just need to clip the sensor in your earlobe or fingerprint. This sensor has an optical heart rate sensor with amplification and circuit for noise reduction giving fast and reliable pulse readings.
