Introduction
Capacitive Fingerprint Reader is a capacitive fingerprint development module dedicated to secondary development and integrated applications, with high speed, fast identification, and high stability.
Capacitive Fingerprint Reader capacitive fingerprint module is based on STM32F105R8 high-speed digital processor, combined with high-security commercial fingerprint algorithm, equipped with advanced semiconductor fingerprint sensor, and has fingerprint entry, image processing, feature value extraction, template generation, template storage, fingerprint Intelligent integration module for functions such as comparison and search; specializing in scientific research units, fingerprint product manufacturers, and application integration vendors, providing standard secondary fingerprint components for quick and easy integration.
Feature
Easy to use, no need to understand fingerprint technology, the internal structure and operation of the module, only a simple command can complete the corresponding operation
Using commercial algorithms, stable performance and fast recognition speed
Sensitive finger sensing, as long as the finger gently touches the collection window, it can be quickly recognized without pressing
Can freely input and output fingerprint pictures, fingerprint feature value files and various fingerprint operations
Provide UART serial port and USB dual communication
With processor power-down sleep, finger induction wake-up function, low power consumption
