Fingerprint Based Security System





Introduction: Fingerprint Based Security System


This AVR microcontroller based project demonstrates Finger print based access control or security system, in this project we have provided all required data, PCB, Code, Circuit Diagram, Proteus Simulation.

This project operates a relay based on valid finger detection. It is provided with 6-Keys for Addition, Deletion of Finger Print. It uses standard SM-630 Fingerprint Verification Module developed by Miaxis Biometrics Co., Ltd.

SM630 background highlight optical fingerprint verification module is the latest release of Miaxis Biometrics Co., Ltd. It consists of optical fingerprint sensor, high performance DSP processor and Flash. It boasts of functions such as fingerprint Login, fingerprint deletion, fingerprint verification, fingerprint upload, fingerprint download, etc.

    can someone share a link for us to download finger print libraries for proteus

    hi..i'm kindda new to this but can you please use the 4*3 keypad for controlling new enrollment and deletion in the AVR code instead of defining buttons??...thanks

    Where do I get the fingerprint library for proteus?? I am not able to find anywhere

    Can you please send me the link or the Library itself?

    Thank You!

    Can you send me fingerprint library for proteus.?
