arduino capacitive fingerprint sensor

Fingerprint algorithm has excellent performance and fast recognition speed


The arduino capacitive fingerprint sensor takes the independent fingerprint chip ID812 processor as the core and uses a capacitive fingerprint sensor. It has ultra-high image quality, small size, low power consumption, fast acquisition speed, good adaptability to wet and dry fingers, and strong anti-counterfeiting capabilities. Runs the IDFinger high-performance fingerprint core algorithm that is widely praised in the industry. It not only recognizes fast and accurate, but also has adaptive fingerprint recognition technology. It has the functions of learning and self-improvement. When the fingerprint changes, the new fingerprint characteristics are automatically stored In the product, the purpose of automatically adapting to changes in fingerprints is achieved. It adopts standard USB/UART communication, simple structure, small size, and can be flexibly embedded in various products with limited size. Support Windows, Embedded and Android systems.
