The AS608 Optical Fingerprint Sensor Module is a high-performance biometric authentication device designed for secure fingerprint recognition and identity verification applications. With its advanced optical sensing technology, fast processing speed, and high accuracy, the AS608 fingerprint module is an ideal choice for Arduino, Raspberry Pi, STM32, ESP32, and other microcontroller-based projects. Whether you are developing an access control system, attendance machine, smart lock, or security application, the AS608 provides reliable and efficient fingerprint recognition in a compact form factor.

Advanced Optical Fingerprint Recognition Technology

The AS608 uses optical fingerprint scanning technology, which captures high-resolution fingerprint images by detecting light reflection from finger ridges and valleys. This method ensures stable performance, strong anti-interference capability, and long-term durability, making it suitable for both indoor and semi-industrial environments.

Unlike capacitive sensors, optical fingerprint sensors are less affected by static electricity and are known for their consistent accuracy across different finger conditions. The AS608 delivers precise fingerprint imaging even with dry or slightly worn fingers.

High Accuracy and Fast Response Time

Equipped with an advanced onboard processor and fingerprint algorithm, the AS608 fingerprint sensor module offers fast fingerprint enrollment, matching, and identification. It can store multiple fingerprint templates internally and perform 1:1 or 1:N matching directly on the module, reducing the processing load on the main microcontroller.

This results in:

• Quick fingerprint recognition

• Low false acceptance rate (FAR)

• Low false rejection rate (FRR)

These features make the AS608 ideal for security-sensitive applications where speed and reliability are critical.
