Schematic PCB

Fingerprint password lock based on 51

This design developed a fingerprint recognition electronic password lock system based on a single-chip microcomputer. The system uses STC89C52 microcontroller as the core of the module. It controls the ZFM-60 fingerprint module through serial communication to register fingerprints and store fingerprint data. It displays the comparison process and results through the HS12864-15C LCD, supplemented by DC relays and light-emitting diodes to simulate unlocking. Actions. This system has small size, high cost performance, fast transmission speed, and is suitable for families and organizations.
