Designing a Door Access Control System with Programmed AT89C52 Microcontroller

Abstract: Biometric door systems present limitations as they are unsuitable for widespread use due to hygiene concerns and accessibility issues for individuals with physical disabilities. To address these challenges, a novel approach was devised utilizing an AT89C52 microcontroller-based access door control system, integrating dual-factor authentication via password and smartcard. Unified Modeling Language was employed to

Unlock a Door with your Fingerprint

We built a biometric fingerprint-controlled lock prototype. A fingerprint scanner is used to capture and store the fingerprints of authorized users. When the scanner recognizes a user, a solenoid plunger disengages and opens the lock.Parts List: The fingerprint scanner module is powered by an ARM Cortex M3 CPU, which controls the on-board optical sensor and
