Product Description

The R307 Fingerprint Sensor Module is a professional-grade biometric solution that combines high-speed image processing with a robust optical sensor. This all-in-one module handles fingerprint collection, template extraction, and matching internally, offloading complex computational tasks from your microcontroller. Featuring a high-quality optical glass window, it provides superior durability and performance compared to capacitive alternatives. Whether you are developing a smart door lock, a biometric attendance system, or a secure locker at your Pimpri workshop, the R307 offers a reliable and easy-to-integrate security layer for any embedded project.

Detailed Key Features

  • Integrated DSP Processor: Features a built-in high-speed Digital Signal Processor (DSP) that manages fingerprint algorithms, template generation, and searching autonomously.

  • Large Template Storage: Onboard memory supports up to 1000 distinct fingerprint records, allowing for multi-user security deployments in offices or small residential complexes.

  • Dual Interface Logic: Primarily operates via a standard UART serial interface for microcontrollers but also supports a USB 1.1 interface for direct PC connectivity.

  • Adjustable Security Levels: Allows developers to configure the "Security Level" (matching threshold) from 1 to 5 to balance between speed and false-acceptance rates.

  • Compact & Rugged Design: The optical sensor is housed in a heavy-duty enclosure designed to resist physical wear and environmental light interference.


All Technical Details

  • Resolution: 500 DPI for high-detail fingerprint imaging.

  • Operating Current: ~50mA (Peak: 120mA during scan).

  • Matching Mode: Supports both 1:1 (Verification) and 1:N (Identification) matching.

  • False Acceptance Rate (FAR): < 0.001% (Security Level 3).

  • False Rejection Rate (FRR): < 1.0% (Security Level 3).

  • Dimensions: Approx. 45mm x 20mm x 18mm.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Wiring Logic: To connect the R307 to an Arduino, cross the serial lines: Sensor TX to Arduino RX (Pin 2 if using SoftwareSerial) and Sensor RX to Arduino TX (Pin 3).


  • Touch Sensitivity: The R307 features a "Touch" (WAKE) pin. In battery-operated projects, keep the sensor in sleep mode and use this pin to trigger an interrupt when a finger is placed on the glass to save significant power.

  • Enrolling Process: For the best matching accuracy, always enroll a finger twice during the initial setup as prompted by the library; this allows the DSP to create a more robust template.

  • Glass Maintenance: Keep the optical glass clean using a microfiber cloth. Dust or oil buildup on the sensor surface is the most common reason for failed fingerprint reads.

Package Includes

  • 1 x R307 Optical Fingerprint Sensor Module
