🛡️ R307 Optical Fingerprint Sensor Module – Biometric Security for Arduino & Embedded Systems

Description

🔒 R307 Optical Fingerprint Sensor Module – High Accuracy Biometric Scanner for Embedded Security

The R307 Optical Fingerprint Sensor Module is a compact and highly accurate biometric scanner designed for secure fingerprint recognition and enrollment in embedded systems. It uses advanced optical sensing and a built-in digital signal processor (DSP) to capture and process fingerprint images quickly and accurately. Whether you’re working on a biometric attendance system, access control device, or a custom IoT-based security solution, the R307 is a trusted choice for developers and hobbyists.

Engineered for seamless integration with Arduino, ESP32, Raspberry Pi, and various microcontroller platforms, this sensor simplifies biometric authentication through UART serial communication. The internal flash memory can store up to 1,000 unique fingerprint templates, allowing both 1:1 verification and 1:N identification.

🔍 Key Features:

• ✅ Optical Fingerprint Imaging: Captures fingerprints with precision using optical sensing technology. The sensor surface is protected by a durable transparent acrylic lens.

• ✅ Built-in DSP Processor: Processes fingerprint image, performs feature extraction, and matches fingerprint data internally without needing external processing.

• ✅ User-Friendly Integration: Communicates over UART (TTL) at 9600 bps (configurable), easily interfaced with Arduino, ESP8266, STM32, or Raspberry Pi.

• ✅ High Storage Capacity: Can store up to 1,000 fingerprint templates in its onboard flash memory, making it suitable for multi-user environments.

• ✅ Fast Matching Speed: Typical image processing and fingerprint matching take less than 1 second, allowing near-instant authentication.

• ✅ Two Matching Modes:

  • 1:1 for direct comparison

  • 1:N for database search

• ✅ Security Features: Supports command-based operations such as enroll, search, delete, and read system parameters with password protection.

• ✅ LED Control: The module includes a controllable onboard LED that lights up during scanning for visual feedback.
