AS608 Door Lock Fingerprint Sensor

Dedicated optical fingerprint sensor module (AS608) for secure, standalone access control in door lock and gate entry applications. Operates at DC 3.3V with efficient power usage. Dimensions conform to industry-standard AS608 layout (~32 × 28 × 20 mm); lightweight and mechanically robust. Captures fingerprint images using optical prism-based sensing, then applies deterministic algorithms to detect and encode ridge patterns and minutiae points. During registration, two distinct scans are fused into one resilient composite template stored in protected internal memory. Matching modes include fast 1:1 verification and scalable 1:N identification — both executed entirely on-module. Communication is via UART at 3.3V logic level; no external processing or cloud connectivity required for core functionality.
