Fingerprint scanners are awesome. Why use a key when you have one
right at the tip of your finger? Unfortunately, they’re usually
unreliable or difficult to implement. Well not anymore! We’ve
found this great fingerprint module from ADH-Tech that
communicates over TTL Serial so you can easily embed it into your
The module itself does all of the heavy lifting behind reading
and identifying the fingerprints with an on-board optical sensor
and 32-bit CPU. All you need to do is send it simple commands. 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 fingerprint scanner
can store different fingerprints and the database of prints can
even be downloaded from the unit and distributed 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!
This is the more economical version of the GT-511 which has a
decreased memory capacity (compared to the GT-511C3). The module
can only store up to 20 different fingerprints but is capable of
360° fingerprint recognition and download and upload templates
using serial interface. If you are on a budget and need only a
small number of fingerprints stored, this is the perfect option
The module is small and easy to mount using two mounting tabs on
the side of the sensor. The on-board JST-SH connector has four
signals: Vcc, GND, Tx, Rx. A compatible JST-SH pigtail is
included. Demo software for PC is available in the documents
below, simply connect the module to your computer using an FTDI
Breakout and start the software to read fingerprints!
