Description

 Fingerprint sensor: We have used R305 Finger Print Sensor. It has an Optical biometric fingerprint reader. It also has inbuilt flash memory. It performs the function of image processing and gives out data on its output pin.

2) Microcontroller: This is the CPU (central processing unit) of our project. We are going to use a microcontroller of 8051 family. The various functions of microcontroller are like:

I. Reading various digital input signals from fingerprint sensor
II. Sending this data to LCD so that the person operating this project should understand the status.
III. Giving the respective signal to the various output devices. Relay and DC motor for valid access and buzzer for the invalid access.
IV. Sending the data to the computer using serial port. This data consist of the status of valid or invalid access

3) LCD Display: We have used 16×2 alphanumeric Liquid Crystal Display (LCD) which means it can display alphabets along with numbers on 2 lines each containing 16 characters.

4) Buzzer: We are going to use a buzzer to indicate the invalid access to open the door.

5) Keypad: User will enter various commands using the keypad. Various keys of keypad are as following,
I. Add fingerprint entry II. Search fingerprint III. Empty the database of fingerprint module

Applications and Advantages:

1. Industrial application: “Fingerprint based security system” project can be used by the employees, staff or workers in various industries like Automobile industries, manufacturing industries, Software development
