Description

This sensor module integrates a semiconductor capacitive fingerprint sensor with a dedicated high-performance processor running the IDfinger6.0 algorithm. This architecture allows the module to perform all fingerprint processing onboard—including image capture, feature extraction, template storage, and matching—freeing the host microcontroller from computational load. The capacitive sensing technology provides reliable imaging of fingerprint ridges and valleys.

Designed for secure embedded systems, the module supports 360-degree fingerprint recognition and features deep self-learning capabilities to improve matching accuracy over time. It operates within an environmental range of -10°C to 60°C and 20% to 80% relative humidity. The compact form factor, with a 19mm diameter sensing area, makes it ideal for integration into access control panels, secure containers, and identity verification devices.

Key Features

  • Onboard fingerprint algorithm (IDfinger6.0) for fully independent enrollment, storage, and matching.
  • High-security capacitive sensing technology resistant to spoofing with prints or images.
  • Compact and durable construction with a 19mm diameter sensing surface and FPC connector.
  • Supports 360-degree fingerprint placement and features adaptive self-learning for improved recognition rates.
  • Low-voltage 3.3V operation with minimal power consumption for battery-powered applications.
  • Includes comprehensive software support: DFRobot Arduino library and upper computer configuration software.
  • Robust environmental specification for reliable operation in varied indoor conditions.

Applications

  • Biometric access control systems for doors, safes, and secure drawers.
  • User authentication and ID recognition in attendance systems, vending machines, or personal devices.
  • Authorization and login security for industrial equipment, data loggers, or medical instruments.
  • Embedded security for DIY electronics projects, robotics, and maker prototypes requiring user verification.

Frequently Asked Questions

What is the operating voltage and current requirement for this fingerprint sensor?

The sensor operates strictly at 3.3V DC. Exceeding this voltage can damage the module. Under typical operation, it draws less than 40mA of current, making it suitable for powering directly from a microcontroller's 3.3V pin or a regulated low-voltage supply.

How do I communicate with this sensor and what is the pinout?

Communication is via a standard UART (serial) interface. The 6-pin FPC connector provides pins for VCC (3.3V), GND, TX (sensor transmit), RX (sensor receive), and two touch detection pins. You must use a logic-level compatible UART port on your microcontroller (3.3V logic). The included FPC adapter converts the connector to standard pin headers for easy breadboarding.

What is the fingerprint enrollment and matching process?

The module handles all processing internally using its onboard IDfinger6.0 algorithm. You send high-level commands via UART to enroll a new fingerprint (which requires multiple placements), delete a stored template, or initiate a 1:N search. The sensor returns a match ID or failure status, completing a 1:N match against its 80-template database in under 0.5 seconds.

Does this sensor work with Arduino or Raspberry Pi?

Yes, it is fully compatible with 3.3V logic boards like Arduino (using a 3.3V variant or level shifter), Raspberry Pi, ESP32, and others. DFRobot provides a dedicated Arduino library to simplify command handling for enrollment, deletion, and matching functions. For Raspberry Pi, you can use serial communication via USB-UART adapters or GPIO UART pins.

What is included in the package and what is the FPC adapter for?

The package includes the fingerprint sensor module with an FPC connector, a flexible 0.5mm pitch 6-pin FPC cable, and an FPC-to-pin-header adapter board. The adapter board is essential for connecting the flexible cable to standard 2.54mm pitch male headers, allowing you to plug the sensor directly into a breadboard or connect it to Jumper wires for prototyping.

Package Includes

  • 1 x UART Capacitive Fingerprint Sensor Module (with FPC Connector)
  • 1 x 0.5mm Pitch, 6-Pin FPC Cable
