Introduction:
UART Fingerprint Reader is a new fingerprint development module dedicated to secondary development and integrated applications, with high speed, fast identification and high stability.
The UART Fingerprint Reader module takes the STM32F205 high-speed digital processor as the core, combines commercial fingerprint algorithms, high-precision optical sensors, and is an intelligent type with functions such as fingerprint entry, image processing, feature value extraction, template generation, template storage, fingerprint comparison, and search. Module; provides UART interface and communication protocol, specially provides standard secondary development fingerprint kits for scientific research units and application integration manufacturers, which is fast and easy to integrate applications!
Feature:
The fingerprint sensor is sensitive and the recognition speed is fast: the fingerprint module uses a high-precision optical path and imaging element. When using it, you only need a finger to lightly recognize it.
Strong stability: using ST's STM32F205 advanced digital processing chip as a processor, low power consumption, fast and stable, at least 30% more stable than domestic chips and chips of other platforms.
Scientific structure: using split structure, fingerprint sensor + processing motherboard + algorithm platform, the motherboard is stable;
Use standard 16P universal interface; the sensor can independently choose and replace optical and semiconductor sensors;
Using commercial algorithms, fast.
Easy to develop: serial UART operation (connect directly to any microcontroller with a serial port), simple operation, and equipped with PC demo, learning software, related tools and microcontroller routines.
Open: You can freely input and output fingerprint pictures, fingerprint feature value files and various fingerprint operations. The protocol is more complete and the opening is better.
Applications:
Fingerprint product development: development of fingerprint lock, fingerprint safe, fingerprint access control, fingerprint attendance
Fingerprint integration application: development of fingerprint locks, integrated in various security products, such as intercom, switch, personnel identification, authority management
