Fingerprint Module R307

The R307 Fingerprint Sensor Module lets you capture, store, and verify fingerprints with high accuracy and reliability. It’s ideal for security systems, door locks, attendance systems, and access control projects using Arduino, Raspberry Pi, or STM32 . This module uses an optical fingerprint recognition system that captures clear and detailed fingerprint images under various lighting conditions. It can store up to 1000 fingerprints in its internal memory, allowing easy management and verification. The R307 communicates through UART (serial interface) , making it simple to integrate with microcontrollers and development boards. You can enroll, search, or delete fingerprints directly through serial commands or with ready-made Arduino libraries. Because it includes built-in image processing algorithms , the R307 delivers fast identification speeds and low error rates . It also features LED indication and an anti-fake detection system , ensuring secure and stable performance. Key Features: Model: R307 Optical Fingerprint Sensor Interface: UART (Serial Communication) Stores up to 1000 fingerprint templates Operating Voltage: 3.6V–6V DC Fast fingerprint matching and verification Built-in image processing and anti-fake detection Compatible with Arduino, Raspberry Pi, STM32, and other MCUs Ideal for door locks, attendance systems, and access control The R307 Fingerprint Module helps students, hobbyists, and engineers build fast, accurate, and secure biometric identification systems with ease.
