Fingerprint Scanner GT-511C3 3V TTL
This fingerprint scanner GT-511C3 from ADH-Tech communicates over TTL Serial so you can easily embed it into your next project.
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!
The module can store up to 200 different fingerprints and is capable of 360° recognition. If your’e on a tigher budget we got the GT511C1R.
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: Tx, Rx Vcc, GND. 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!
Note: This fingerprint scanner operates as 3.3v TTL, you’ll need a logic level converter, or resistor divider circuit to connect it to a 5v device such as the Arduino Uno.
