This is fingerprint recognition sensor with uart TTL serial port and it is easy to use.

The Fingerprint Sensor Adapter module and the 6pin cable make the Fingerprint sensor compatible with Arduino.

It can be used to secure your project with biometrics – this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. These modules are typically used in safes such as drawers, door.

There is a high powered DSP chip that does the image rendering, calculation, feature-finding and searching. Connect to the micro controller or system with TTL serial, and send packets of data to take photos, detect prints, hash and search. You can also enroll new fingers directly – up to 500 finger prints can be stored in the onboard FLASH memory.


– The 6P cable help you to connect the sensor to OPEN-SMART ATmega328P development board
