Fingerprint Sensor Based Security System
Project Pictures
Description:
Finger print based security system can be used at many places like Industries, Offices, and Colleges or even at our home. This project is a fine combination of “Biometrics technology” and “Embedded system technology”. Fingerprint sensor is the main part of this system. It makes use of Biometric sensor to detect fingerprint. It is also called as Biometric sensor. Fingerprint sensor uses various types of techniques like ultrasonic method, optical method or thermal technique. In this project we have used optical fingerprint sensor.
Main blocks of this project are Microcontroller, Fingerprint module, Buzzer, Relay, Keypad, LCD display and Motor. User has to place his/her finger on the optical sensor part of fingerprint module. We have seen Password based security system RFID based security system. The main feature or speciality of fingerprint is that it is unique. It gives this project the high level security than other security systems. Person recognition using the Fingerprint identification is used since a long time. Most common example is use in the criminal cases.

Description in detail:
Following are the important blocks of this system:
1) 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 companies.
2. Home or domestic application: This project can be used to automate the door locking process at our home, so the user need not to carry the door lock keys along with him, he can just use his/her finger to open the door
3. Bank Lockers or security safes: Many of the banks use key based or password based locks for their lockers or safes. We can implement Fingerprint based bank locker system using this project.
Advantages:
1. Fingerprint based security system is most secured system as compared to other systems. Reason is that RFID card or Keys of lock can be stolen, password may be leaked. However thumbnail of every human being is unique, so lock will not open unless the same person is present to give the impression of fingerprint.
2. No need to carry the keys to open the lock. Or even there is no need to remember the password or any Pin number.
3. One of the main advantages is that this system remembers the stored password even if the power supply is turned off.
4. Scientific research and studies have proved that fingerprints do not change as you grow up.
5. Using Fingerprint saves time to gain access as compared to other methods like RFID card, Password or Key.
Future Development:
1. We can send this data to a remote location using mobile or internet
2. We can use non-contact fingerprint sensor. Which is also called as touchless 3D fingerprint scanner.
3. We can implement other related modules like fire sensor, GSM modem.
