AS608 Biometric Fingerprint Reader Sensor Price in Sri Lanka

The AS608 Biometric Fingerprint Sensor (JM-101B) is a compact and reliable optical fingerprint recognition module designed for secure identification systems. Equipped with an onboard DSP processor, it handles image acquisition, feature extraction, and template matching autonomously—reducing load on the host microcontroller. With support for both 1:1 and 1:N matching modes, it’s an ideal solution for biometric door locks, attendance trackers, and embedded authentication platforms. Its low power requirements, fast recognition speed, and flexible UART/USB interfacing make it a favorite among hobbyists and engineers building secure systems on platforms like Arduino or Raspberry Pi.
