INDUSTRIAL-PROJECT ON “ Finger Print Based Time attendance system ” Presented By:- Shaikh Shahzad Adil Dyanand Lawty Waghmare Sachin Atul Tamsekar Amar Chitte

Short Introduction to over project Registering the attendances of students have became a hectic work as sometimes their attendance may be registered or missed. To overcome this problem i.e. to get the attendances registered perfectly we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS.

What’s embedded ? An embedded system is some combination of computer hardware and software, either fixed in capability or programmable, that is specifically designed for a particular function. Industrial machines, automobiles, medical equipment, cameras, household appliances, airplanes, vending machines and toys (as well as the more obvious cellular phone and PDA) are among the myriad possible hosts of an embedded system. Embedded systems that are programmable are provided with programming interfaces, and embedded systems programming is a specialized occupation.

What’s Bio-Metrics ? Biometrics is the science and technology of measuring and analyzing biological data. In information technology, biometrics refers to technologies that measure and analyze human body characteristics, such as DNA, fingerprints, eye retinas and irises, voice patterns, facial patterns and hand measurements, for authentication purposes. Authentication by biometric verification is becoming increasingly common in corporate and public security systems, consumer electronics and point of sale (POS) applications. In addition to security, the driving force behind biometric verification has been convenience.

Requirements of over project Software:Embedded C, Keil, Proload Microcontroller:AT89S52 Power Supply:+5V, 500mA Display:LED 5mm, 16 X 2 LCD Crystal: MHz Biometric Sensor:FIM3030N Storage Capacity:Up to 100 finger print images Image Registration:Through Serial Communication 

Definition of Embeded C The use of C language to program microcontrollers is becoming too common. And most of the time its not easy to build an application in assembly which instead you can make easily in C. So Its important that C language for microcontroller which is commonly known as Embedded C. As we are going to use Keil C51 Compiler, hence we also call it Keil C. Embedded C is an extension to the C programming language aimed at providing support for high level - high performance programming of DSP processors in C.

About Microcontroller AT89S52 About Microcontroller AT89S52 8-bit Microcontroller with 8K Bytes In-System Programmable Flash The AT89S52 is a low-power, high-performance CMOS 8-bit Microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmels high-density nonvolatile memory technology and is compatible with the indus try-standard 80C51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in- system or by a conventional nonvolatile memory pro- grammer. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful Microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications.

About LED,s5mm and LCD 16 x 2 LEDs emit light when an electric current passes through them. 16 x 2 Character LCD's all with Back light have the standard HD44780 type controller for interfacing to a microcontroller or similar.

About Biometric Sensor Biometric sensor combines the physical traits of human body with digital technology to give birth to biometric security. These semiconductor devices are provided with template database and algorithms to match live biometric samples with those stored in the database. Needless to say, various fields around us have been touched by the usefulness of these devices and more application areas are being discovered. Tagged as state- of-the-art biometric devices, you can depend upon them for high recognition accuracy. Features of Biometric Sensor * Distinct algorithms are installed in a biometric sensor to ensure precise user authentication as the output. * Analog to digital converters are main features of these devices, which convert biometric analog data to digital codes. * The physical traits, like fingerprints, face metrics, vein structures in hands and others are used by these devices to prepare templates. * Fast identification and verification are included in the list of features offered by these biometric security devices. * These devices are available in three different categories, including semiconductor sensors, optical sensors and ultrasound sensors.

Modules Of Biometric sensor This module can operate in 2 modes they are Master mode and User mode. We will be using Master mode to register the fingerprints which will be stored in the ROM present on the scanner with a unique id. When this module is interfaced to the microcontroller, we will be using it in user mode. In this mode we will be verifying the scanned images with the stored images. When coming to our application the images of the students will be stored in the module with a unique id. To register their attendance the students have to scan their image which is then verified with the image present in fingerprint module and their attendance is registered for that day.

Working of 8051 microcontroller This scanner is interfaced to 8051 microcontroller through max232 enabling serial communication.. By using this controller we will be controlling the scanning process. After the scanning has been completed the result is stored in the microcontroller. By simply pressing a switch we can get the list of absentees for that day.

Power supply This project uses regulated 5V, 500mA power supply three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.

Advantages: No manual errors No false attendance Need not remember any password Need not to carry any card

Scopes for Advancements GSM modem can be connected to this unit to communicate to the parents / HR Department, in case of absence of the candidate. RTC can be interfaced to record login and logout time.

Applications Industries are using finger print modems for access control, Stores, attendance recording, and machine operation authentication. Banks and ATM Voter Identification and electoral enrollment Personal Computers Automotives and high end cars
