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. This sensor 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.
This video shows how to interface fingerprint sensor using M5Stack Core ESP32 Development Kit.
This is the list of items used in the video.
Since the code is quite long, I divide into 3 files. 2 files with a named “Fingerprint” are the library and “M5StackFingerprint” is the main file. You can refer to the video tutorial on how to use the code.
