Fingerprint Identification Module Overview This compact, metal fingerprint identification module integrates image collection and an onboard algorithm chip to provide a complete biometric input solution for embedded systems and access control. It is suitable for developers and integrators who need a lowpower, fast, and easytoinstall fingerprint sensor. Key benefits Integrated design combines sensor and algorithm chip for simplified system integration and faster development. Fast fingerprint capture and recognition: image entry in 0.3 seconds and typical search time of 0.3 s for 1:1000 comparisons. Low power operation: works from DC 3.3V with typical current around 30 mA and peak 40 mA. Compact footprint: small acquisition window and installation diameter for easy mounting in panels or housings. Reliable identification: Safety Level 5 with a false accept rate of 0.0001% and a false reject rate of 1.0%. Standard serial interface: RS232 TTL 3.3V for straightforward connectivity to microcontrollers and controllers. Features and technical highlights Item type: Fingerprint Identification Module Material: Metal Color: As picture shown Power supply: DC 3.3V Operating current: 30 mA (typical), peak current: 40 mA Fingerprint image entry time: 0.3 seconds Acquisition window area diameter: approx. 15 mm / 0.6 in Installation diameter: approx. 19 mm / 0.7 in Image size: 192 x 192 pixels Image resolution: 508 dpi Matching modes: Comparison method 1:1 and search mode 1:N Storage capacity: 200 pcs Safety level: Level 5 (scale from low to : 1, 2, 3, 4, 5) FAR: 0.0001%, FRR: 1.0% Search time: 0.3 s (1:1000, mean value) Upper interface: RS232 (TTL logic level, 3.3 V) Communication baud rate: 9600 x N bps, N = 112 (default N = 6, 57600 bps) Working environment: temperature 20 to +45 degrees C; relative humidity 10% RH to 85% RH (no condensation) Practical applications Access control and smart locks: Integrate into door panels or lock bodies where a small installation diameter is required. Time and attendance terminals: Use in compact attendance readers for small offices or workstations to store and verify up to 200 fingerprints. Embedded systems and industrial controls: Connect via RS232 TTL to microcontrollers, security panels, vending machines, or other equipment requiring reliable biometric input. What is included 1 x Fingerprint Identification Module Notes for integration Interface levels are TTL 3.3 V; ensure host device serial port is compatible or use a suitable level shifter. Allow sufficient mounting depth and clearance for the installation diameter of approximately 19 mm. Maintain operating environment within specified temperature and humidity ranges to avoid condensation. This module provides a compact, lowpower biometric sensor with onboard processing for straightforward integration into access, attendance, and embedded control systems.
