Product Overview

The GT-511C3 FPS (fingerprint scanner) 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 provides the modules functionality which automatically processes the scanned fingerprint. The module can be used in projects for identifying users, for example allowing access through a door by scanning a finger print instead of using a key. 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 user can store the finger print data in the module and can configure it in 1:1 or 1: N mode for identifying the person. This module can directly interface with any 3.3V or 5V microcontrollers, but a suitable level converter/serial adapter is required for interfacing with the serial port of a PC. A logic level converter is a mediator so that two devices can communicate which works on different voltage level.
