An optical fingerprint sensor module is a biometric device that captures fingerprint images using optical imaging technology and performs fingerprint recognition through integrated processing and matching algorithms. It combines image acquisition, feature extraction, template storage, and comparison in a single embedded module.
Optical fingerprint sensors offer stable image quality, good resistance to environmental interference, and consistent performance across different users. They are widely used in access control and embedded systems due to their reliability and mature technology.
The module supports a fingerprint template capacity of up to 500 or 3000 fingerprints, depending on the selected configuration. This makes it suitable for both small-scale and medium-size biometric systems.
Yes. The optical fingerprint sensor module supports both 1:1 verification and 1:N identification modes. In 1:N mode, matching against 500 stored templates can be completed in under 0.5 seconds.
At the default security level, the module delivers a False Accept Rate (FAR) of less than 0.001% and a False Reject Rate (FRR) of less than 2%, providing a good balance between security and user convenience.
Yes. The security level can be configured from Level 1 to Level 5. Higher levels increase security by applying stricter matching thresholds, while lower levels improve recognition tolerance in demanding environments.
The module communicates through a standard UART interface with 3.3V TTL logic levels. A USB interface is also available as an optional configuration for systems that require USB communication.
Yes. The compact size, low power consumption, and standard serial communication make this optical fingerprint module well suited for embedded systems, including access controllers, electronic locks, and industrial terminals.
The module is designed to operate in temperatures from -10°C to 60°C, with a relative humidity range of 20% to 80%. This allows stable operation in most indoor and semi-outdoor environments.
Yes. Detailed command protocols, integration guides, and technical support are available to assist with system development and product integration.
