Introduction
This project is about solving the problem regarding security of unauthorized people trespassing in
our home, shops or offices.
Security issues can be fixed using traditional locks but there is always possibility of someone
opening the lock even without breaking it with the use of duplicate key.
Using these kinds of locks also create problem if we lose keys and also we have to carry keys
along with us always.
Again, using patterns in the locks can increase security but again it can be opened if somehow the
passwords or patterns are known.
So, leaving every system in this project we will implement a system using biometrics.
In case of biometrics,the pattern which will be used as key will be unique.
Here, to implement the project we will use fingerprint as the key.

ESP32
ESP32 is a series of low-cost, low-power system on a chip
microcontroller with integrated Wi-Fi and dual-mode Bluetooth. The
ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in
both dual-core and single-core variations, Xtensa LX7 dual-core
microprocessor or a single-core RISC-V microprocessor and includes
built-in antenna switches, RF balun, power amplifier, low-noise receive
amplifier, filters, and power-management modules.

Relay Module
Relay is an electromechanical device that uses an electric current to
open or close the contacts of a switch. The single-channel relay
module is much more than just a plain relay, it comprises of
components that make switching and connection easier and act as
indicators to show if the module is powered and if the relay is active or
not.

Magnetic Door Lock
An electromagnetic lock, magnetic lock, or maglock is a locking device that
consists of an electromagnet and an armature plate. ... A fail-secure locking
device remains locked when power is lost. Fail-safe locking devices are
unlocked when de-energized. Direct pull electromagnetic locks are
inherently fail-safe.

16*2 LCD Display
A 16x2 LCD means it can display 16 characters per line and there are 2 such
lines. In this LCD each character is displayed in 5x7 pixel matrix. This LCD
has two registers, namely, Command and Data.

Fingerprint sensor
R307 Fingerprint Module consists of optical fingerprint sensor, high-speed
DSP processor, high-performance fingerprint alignment algorithm, high-
capacity FLASH chips and other hardware and software composition, stable
performance, simple structure, with fingerprint entry, image processing,
fingerprint matching, search and template storage and other functions.

Programming in C
C is highly portable and is used for scripting system applications which form a
major part of Windows, UNIX, and Linux operating system. C is a general-
purpose programming language and can efficiently work on enterprise
applications, games, graphics, and applications requiring calculations, etc.

Future Work
1. We can add Iot Internet of Things with this project
that the situation can be observed from anywhere.
2. In future we can add multiple security system like
password and camera.
3. In future we will upgrade it using mobile app based.

Conclusion
In this project we have tried to solve the security matter in door by bringing the concept of
biometrics along with the door lock. So, for that purpose we are using finger prints as unique
key to implement a device so as to lock or unlock a door. We have discussed about the
different components using arduino we would require to implement our project we have
given the hardware and software requirements in the project.
