1. Under the guidance of : Dr. Manish Tiwari ( Associate Professor) Submitted By : Puneet K umar V erma P Venkata Sai Mohan Tadpally Vinay Kumar Fingerprint Based Lock System

2. Objective: The objective of this project is to design a smart door access system using fingerprint sensor module and provide access to only authorized persons . And an emergency beep sound is added to give alarm if any unauthorized person intrudes into the system or if anyone try to break the lock.

3. Tools and Components Used:- Arduino UNO board Arduino IDE Fingerprint sensor Solenoid Lock LCD display Relay Power Supply Buzzer Bread Board Jumper Wires

4. Tools and components used:- Arduino uno Finger print Sensor Relay Breadboard and Jumper wires

5. Tools and components used:- Solenoid Lock LCD Buzzer Battery

6. Block diagram:- Arduino LCD Fingerprint sensor Buzzer Solenoid lock gate Power supply

7. Information about fingerprints:- A fingerprint is formed by the impression of the friction ridges on the finger of a human. The matching of two fingerprints is amongst the most widely used and reliable biometric techniques. There are three basic fingerprint pattern- Arch Loop Whorl

8. Types of fingerprint scanner:- There are four types of fingerprint scanner- Optical scanners Capacitive scanners Ultrasonic scanners Thermal scanners

9. Finger Print Sensor R307:- R307 Fingerprint Module consists of optical fingerprint Sensor, high-performance fingerprint alignment algorithm, simple structure, stable performance, with fingerprint entry, fingerprint matching,Low power consumption. Finger print sensor

10. Solenoid lock:- Solenoid lock is basically a electromagnet. It is made up of a big coil of copper wire with an armature(a metal) in the middle. Normally the lock is active so we can’t open the door because the solenoid slug is in the way. It does not use any power in this state. When voltage is applied, the slug pulls in so it doesn’t stick out anymore and the door can be opened.

11. Features:- Our lock is fingerprint based so there is no need of key , RFID card or password. Fingerprint based security system is most secured system as compared to other system. Since scientific research and studies have proved that fingerprints do not change as we grow up. Our system stored password even if the power supply is turned off. If the fingerprint doesn’t match , the buzzer will buzz once, but If wrong fingerprints are tried more than five times then it will continue to buzz the buzzer to alert the neighbour that something is wrong.

12. Overview of project:- In the very beginning a fingerprint of main user(Admin) is stored. With the help of this fingerprint other finger prints can be added and removed from the system. In case of fingerprint match the door will open and if not then error message will be displayed on the LCD. Total number of users who can access the lock vary with fingerprint sensor. In our case we are using R307 which can store upto 1000 fingerprints. In case anyone try to break the lock the buzzer will start ringing.

13. Workflow:-

14. Further scope in this project after completing basics:- In place of buzzer that we are using for ringing alarm if some unauthorized person try to break the lock , we can develop such a mechanism so that authorized person get some kind of notification on his mobile phone irrespective of where the authorized person is. A memory based system can be added to store the real time information about all the users who will open the lock.
