Product Description

Fingerprint scanners are awesome. Why use a key when you have one right at the pointer of your finger? Regrettably, they’re normally undependable or difficult to implement. Well not anymore! We’ve discovered this fantastic finger print module from ADH-Tech that interacts over TTL Serial so you can easily embed it into your next task.

The module itself does all the heavy lifting behind reading and determining the fingerprints with an on-board optical sensor and 32-bit CPU. All you have to do is send it simple commands. To get started, simply sign up each fingerprint that you wish to store by sending out the corresponding command and pressing your finger versus the reader three times. The finger print scanner can save different finger prints and the database of prints can even be downloaded from the unit and dispersed to other modules. As well as the fingerprint “design template,” the evaluated variation of the print, you can also obtain the image of a finger print as well as pull raw images from the optical sensing unit!

This is the more cost-effective version of the GT-511 which has a reduced memory capability (compared with the GT-511C3). The module can only accumulate to 20 different finger prints but is capable of 360 ° finger print recognition and download and upload templates using serial user interface. If you are on a budget and require only a small number of finger prints stored, this is the best choice for you!

The module is small and simple to mount using two installing tabs on the side of the sensor. The on-board JST-SH port has 4 signals: Vcc, GND, Tx, Rx. A compatible JST-SH pigtail can be discovered in the associated items below. Demo software for PC is readily available in the documents listed below, simply link the module to your computer utilizing an FTDI Breakout and begin the software application to read fingerprints!
