Product Description

Fingerprint scanners are awesome. Why utilize a key when you have one right at the pointer of your finger? Unfortunately, they’re typically undependable or hard to carry out. Well not anymore! We’ve found this excellent finger print module from ADH-Tech that communicates over TTL Serial so you can quickly embed it into your next task.

The module itself does all the heavy lifting behind reading and determining the finger prints with an on-board optical sensor and 32-bit CPU. All you have to do is send it simple commands. To get started, simply register each finger print that you wish to save by sending out the matching command and pushing your finger versus the reader 3 times. The finger print scanner can keep various finger prints and the database of prints can even be downloaded from the system and distributed to other modules. In addition to the fingerprint “design template,” the analyzed version of the print, you can also recover the image of a fingerprint and even pull raw images from the optical sensor!

This is the more affordable variation of the GT-511 which has actually a decreased memory capability (compared to the GT-511C3). The module can only accumulate to 20 various finger prints but can 360 ° fingerprint recognition and download and upload templates utilizing serial interface. If you are on a budget and need only a little number of finger prints stored, this is the best option for you!

The module is small and easy to mount utilizing 2 mounting tabs on the side of the sensor. The on-board JST-SH port has four signals: Vcc, GND, Tx, Rx. A suitable JST-SH pigtail can be discovered in the related products listed below. Demo software application for PC is readily available in the documents listed below, simply connect the module to your computer system using an FTDI Breakout and begin the software application to check out fingerprints!
