This sensor has an optical heart rate sensor with amplification and circuit for noise reduction giving fast and reliable pulse readings.
Biometric sensor using 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.
The sensor can be easily powered up using the arduino 5v pin.
Enroll key is used for enrolling new finger impression into the system and back function as well.
To measure the heart rate you just need to clip the sensor in your earlobe or fingerprint.
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 project we are going to design fingerprint sensor based biometric attendance system using arduino.
In this project we will be interfacing fingerprint sensor with arduino for biometric security system.
All the process is commanded by arduino like taking an image of finger s print convert it into templates and storing as id etc.
Every key has double features.
Simply we will be interfacing fingerprint sensor w.
In this arduino fingerprint sensor project we have used fingerprint sensor module to take finger or thumb impression as input in the system.
