Product Description

Fingerprint scanners are awesome. Why use a secret when you have one right at the idea of your finger? Sadly, they’re usually unreliable or hard to implement. Well not any longer! We have actually found this excellent finger print module from ADH-Tech that communicates over TTL Serial so you can easily embed it into your next project.

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 easy commands. To get started, just sign up each finger print that you wish to keep by sending out the matching command and pressing your finger against the reader 3 times. The fingerprint scanner can store various finger prints and the database of prints can even be downloaded from the unit and distributed to other modules. Along with the finger print “template,” the examined version of the print, you can likewise recover the image of a finger print and even pull raw images from the optical sensing unit!

The module can just save up to 20 different finger prints however is capable of 360 ° fingerprint recognition and download and upload design templates utilizing serial user interface. If you are on a budget plan and require just a small number of finger prints stored, this is the best alternative for you!

The module is little and easy to mount using 2 mounting tabs on the side of the sensing unit. 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 listed below.
