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:-
1. Arduino UNO board
2. Arduino IDE
3. Fingerprint sensor
4. Solenoid Lock
5. LCD display
6. Relay
7. Power Supply
8. Buzzer
9. Bread Board
10. Jumper Wires

4. Tools and components used:-
Arduino uno Finger print
Sensor

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-
1. Optical scanners
2. Capacitive scanners
3. Ultrasonic scanners
4. 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:-
1. 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.
2. In case of fingerprint match the door will open and if
not then error message will be displayed on the LCD.
3. 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.
4. In case anyone try to break the lock the buzzer will start
ringing.

13. Workflow:-
Study about working mechanism of different components
used.
Interfacing the fingerprint sensor and solenoid lock with
the arduino
Buzzer connection for the information in case of
manhandling
Finally connecting all components and finalize hardware
Implementation

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.
