OVERVIEW OF EXISTING SYSTEM 

Locks & Keys



By this we can’t say that we are going to provide good security to our lockers.

2

DRAW BACKS OF PRESENT SYSTEM 

Security is less



Others can steal the user’s entry key

7

MICROCONTROLLER 89S52 microcontroller. 

RAM 256Bytes.



8Kb of flash memory.



The functionality of 89S52 is same as 8051 microcontroller. 8

FINGER PRINT MODULE 

In this we choose “verification” process.



It can operate in 2 modes they are Master mode and User mode.

9

MASTER MODE 

In this mode,we can register our finger image in present of manager.

10

USER MODE 

Compare of input finger print and identified finger print

11

LCD 

We are using 16x2 lcd display



LCD has14 pin

12

13

PASSWORD PROTECTION 

Unique id (password) which is given to user to open his locker with the help of a keypad



Any port was used to handle our alpha-numeric keypad.

14

15

STEPPER MOTOR



Automatically,

locker

will

open

by

stepper

motor(step angle). 

After the work by using reset pin user will secure their locker.

16

17

Buzzer 

It is a signaling device.



It beeps when user mismatch.

21

SCOPE FOR ADVANCEMENTS



GSM modem can be connected to this unit to communicate to security department, in case of unauthorized entry trials.

22

CONCLUSION



This project is used for 100 members, we can also extend the capability for further requirements.
