Rectangle-shaped All-in-one Capacitive Fingerprint Sensor, Small Form Factor, UART, Integrated Fingerprinting Algorithm.

This is a highly integrated rectangle-shaped all-in-one capacitive fingerprint sensor module, which is designed in small form factor. The module is controlled via UART commands, fairly easy to use. Its advantages includes fast verification, high stability, and low power consumption, etc.

Based on a high-performance Cortex processor, combined with a high-security commercial fingerprinting algorithm, the UART Fingerprint Sensor (R) features functionalities like fingerprint enrolling, image acquisition, feature finding, fingerprint matching, and so on. Without any knowledge about the complicate fingerprinting algorithm, all you need to do is just sending 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
  • A commercial fingerprinting algorithm, stable performance, fast verification, supports fingerprint enrolling, fingerprint matching, collect fingerprint image, and upload fingerprint feature, etc.
  • Capacitive sensitive detection, just touch the collecting window lightly for fast verification
  • Hardware highly integrated, processor and sensor in one small chip, suit for small size applications
  • 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 Raspberry Pi
