DESCRIPTION
Fingerprint scanners are awesome! Why use a key when you have one right at the tip of your finger? Unfortunately, they’re often unreliable or difficult to implement. Well not anymore! This great GT-521F52 fingerprint module from ADH-Tech communicates over TTL Serial so you can easily embed it into your next project. The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an onboard optical sensor and 32-bit ARM Cortex M3 processor.
To get started, just register each fingerprint that you want to store by sending the corresponding command and pressing your finger against the reader three times. The fingerprint scanner can store different fingerprints, and the database of prints can even be downloaded from the unit and distributed to other modules. In addition to the fingerprint template, the analyzed version of the print, you can retrieve the image of a fingerprint and even pull raw images from the optical sensor!
This module is the upgraded version of the GT-521F32 and can store up to an astounding 3,000 different fingerprints! It is capable of 360-degree fingerprint recognition and downloading/uploading templates using the serial interface. Additionally, the GT-521Fxx series features a resolution of 450dpi, with a false acceptance rate of <0.001% and a false rejection rate of <0.1% while only needing <1.5 seconds to identify a unique fingerprint!
The module is small and easy to mount using four mounting holes surrounding the sensor. The onboard JST-SH connector has four signals: Vcc, GND, Tx and Rx.
Please Note:
- Please be aware that even though this fingerprint scanner is equipped with the same connector used on all of the Qwiic boards, it is NOT Qwiic or I2C compatible. That being said, all Qwiic cables will work for this board.
- A compatible JST-SH pigtail can be found in the Hookup Accessories resources section.
