Fingerprint Scanner GT-511C3 Biometric Sensor Module

The Fingerprint Scanner GT-511C3 Biometric Sensor Module is a small embedded module that consists of an optical sensor mounted on a small circuit board. The optical sensor scans a fingerprint and the microcontroller and software provide the functionality of the module which automatically processes the scanned fingerprint.

The Fingerprint Scanner GT-511C3 Fingerprint Scanner Module with JST SH Connector is a high-performance fingerprint scanner. This optical sensor module is designed for easy integration into applications with serial interface (UART).

The GT-511C3 is a TTL fingerprint scanner and can be accessed by Raspberry Pi, Arduino, or any other Microcontroller using just two wires viz Tx & Rx.GT-511C3 Fingerprint Scanner module has an onboard optical sensor and a 32-bit CPU.

It does most of the heavy work like reading and identifying fingerprints. A simple set of commands has to be sent from your micro-controller and the GT-511C3 fingerprint scanner does the rest of the work.

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 download from the unit and distribute to other modules.

As well as the fingerprint “template,” the analyzed version of the print, you can also retrieve the image of a fingerprint and even pull raw images from the optical sensor. We need two wires are for TX and RX and two wires for power supply (5V). The module can use in projects for identifying users, for example allowing access through a door by scanning a finger instead of using a key.
