Fingerprint scanners are remarkable. Why utilize a secret when you have one right at the idea of your finger? Sadly, they’re normally unreliable or hard to implement. Well not anymore! We’ve discovered this great fingerprint module from ADH-Tech that interacts over TTL Serial so you can quickly embed it into your next job.
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 require to do is send it easy commands. To obtain started, just register each fingerprint that you desire to store by sending the matching command and pushing your finger versus the reader three times. The fingerprint scanner can save up to 20 various finger prints and the database of prints can even be downloaded from the unit and dispersed to other modules. As well as the finger print “template,” the examined version of the print, you can also obtain the image of a finger print as well as pull raw images from the optical sensor!
This is the upgraded version of the GT-511 which has an increased memory capability. The module can accumulate to 200 various finger prints (that’s 10x more than the old version!) and is now capable of 360 ° recognition.
The module is little and simple to install using 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 items listed below. Demonstration software for PC is readily available in the files below, simply connect the module to your computer system utilizing an FTDI Breakout and start the software application to read finger prints!
