Awesome Extras

This fully integrated capacitive fingerprint sensor provides an efficient way for users to capture, process, store, and match fingerprints. Based on a high-performance processor & semiconductor fingerprint sensor, it's equipped with a built-in IDfinger6.0 fingerprint algorithm that enables it to complete fingerprint recognition independently. And when working with the DFRobot Arduino library, the sensor can realize functions like fingerprint entry, deletion, and matching through UART. Also, upper computer software is provided to help users easily operate it.

This low-power sensor comes with a compact size and delicate appearance and offers fast recognition and high security. Moreover, it supports 360-degree view object recognition and deep self-learning.
