The research focuses on improving the security and convenience of door access control systems through the integration of advanced fingerprint recognition technology with Arduino microcontrollers and the GSM module. The reliability and flexibility of Arduino, coupled with the GSM capabilities of SIM900, are utilized to create a robust and efficient solution. Fingerprints are captured and verified using a fingerprint sensor, ensuring precise and personalized access control. The Arduino board acts as the main controller, processing fingerprint data and enabling communication with the GSM module for remote operation. This innovative setup allows authorized users to remotely lock or unlock doors using their registered fingerprints. Key functionalities of the system include fingerprint enrollment, template matching, secure data transmission, and real-time status monitoring. During enrollment, fingerprints are registered and securely stored in the system’s database. Subsequent scans are matched against these stored templates to determine access. Secure and reliable communication is ensured through encrypted data transmission between the door lock system and users’ mobile devices, facilitated by the GSM module. By combining Arduino, fingerprint recognition, and GSM technology, the research provides an effective solution for enhancing door access control systems. The integration of biometric authentication with remote management features offers a secure and user-friendly method for access control, reducing the dependency on traditional keys or access cards. The research’s DIY and open-source approach encourages innovation and customization, promoting continuous improvement in access control technology within the maker community.
