Overview
Based on a high-performance Cortex processor, combined with the high-security commercial fingerprinting algorithm, the UART Fingerprint Sensor (D) features functionalities like fingerprint enrolling, image acquisition, feature finding, template generating and storing, fingerprint matching, and so on. Without any knowledge about the complicated fingerprinting algorithm, all you need to do is just send some UART commands, to quickly integrate it into fingerprint verification applications which require small size and high precision.
Features
Easy to use by some simple commands, you don't have to know any fingerprint technology or the module inter structure.
Commercial fingerprinting algorithm, supports functions like fingerprint enrolling, fingerprint matching, fingerprint image acquisition, and fingerprint feature uploading, stable performance, fast identification.
Capacitive sensitive detection, just touch the collecting window lightly for fast verification.
Highly integrated hardware, processor, and sensor in one small chip, suitable for small size applications.
Narrow stainless steel rim supports 360° Omni-directional verification.
Embedded human sensor, the processor will enter sleep automatically, and wake up when touching, lower power consumption.
Onboard UART connector, easy to connect with hardware platforms like STM32 and RPi.
