Key Features of Finger Print Sensor Module - R307
- High-Resolution Optical Sensor: 500 DPI imaging captures detailed fingerprint patterns for accurate enrollment and matching.
- Onboard DSP Processing: Built-in processor handles fingerprint image capture, feature extraction, template generation, and matching-no external processing required.
- Large Template Storage: Internal flash memory stores up to 1,000 fingerprint templates, enabling standalone operation without a host database.
- Fast Verification: Completes 1:1 matching in under 1 second and 1:N search efficiently across the stored database.
- Ultra-Low False Acceptance Rate: FAR below 0.001% ensures robust security against unauthorized access.
- Simple UART Interface: 4-wire serial connection (VCC, GND, TX, RX) makes integration straightforward with virtually any microcontroller.
- 3.3V Logic Level: Directly compatible with 3.3V platforms like ESP32 and Raspberry Pi; works with 5V Arduino boards via the included wiring harness.
- LED Status Indicator: Built-in backlight illuminates the scanning window, providing visual feedback during enrollment and verification.
- Compact Form Factor: Small footprint (55 x 32 mm) fits easily into enclosures, door locks, attendance systems, and portable devices.
- Well-Documented Protocol: Comprehensive command set for enrollment, search, deletion, and system parameter configuration via serial packets.
Perfect For
- Biometric Door Lock System: Pair the R307 with an Arduino or ESP32 and a solenoid/electric strike to build a fingerprint-activated smart lock for home or office security.
- Employee Attendance System: Combine the sensor with a real-time clock module, LCD display, and SD card or cloud connectivity to create an automated attendance tracker.
- IoT-Enabled Access Control: Integrate with ESP8266/ESP32 and a web dashboard to manage fingerprint enrollment, access logs, and remote lock/unlock over Wi-Fi.
