FINGER PRINT BASED STEPPER MOTOR CONTROL AND ACCESS CONTROL SYSTEM
FINGER
PRINT BASED STEPPER MOTOR CONTROL AND ACCESS CONTROL SYSTEM
ABSTRACT:
According to ancient Greek scripts BIOMETRICS means study of life.
Biometrics studies commonly include fingerprint,
face, iris, voice, signature, and hand geometry recognition and
verification. Among these available biometric traits, Fingerprint proves to be one of the best traits providing good
mismatch ratio and also reliable. The present scenario to operate a bank locker
is with locks which are having keys. By this we can’t say that we are
going to provide good security to our lockers. To provide perfect security and to make our work easier, we are taking the
help of two different technologies viz. EMBEDDED SYSTEMS and
BIOMETRICS. This application will be mostly used in organizations, banks
etc. The persons who are the employees of
that particular organization will be asked to scan their images for the
first time they enter into the organization. After that, whenever the employee
tries to enter into the organization, he has
to scan his image to prove that he is an authorized person to the
organization. Thus, the fingerprint module scans the image and sends it to the microcontroller
The
microcontroller reads the image, compares the image with the already stored images in the database. If the scanned image matches the stored image, the
person is asked to enter the password using the keypad to enter into thecompany throughthe main door. This password will be provided to the employee
by the company. If the password matches, the person
is allowed to enter into the office through the main door. The main door will
be opened by rotating the stepper motor fixed to it. The door closes
automatically after a small delay. If it is not matched, indication is
given to alert the buzzer.
This
project uses regulated 5V, 750mA power supply. 7805 three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is
used to rectify the ac output of secondary of 230/18V step down transformer
ADVANTAGES:
1. Simple
to construct
2. More
economic
APPLICATIONS:
1. Home
2. Bank
