#Sfg demo fingerprint software
Start up the SFGDemo software and click Open Device from the bottom left corner. You'll have to cut, strip and solder the wires. If your sensor has different wires, The first wire from the left should be the black wire ground, then the two data pins, RX is the white wire, TX is the green wire then the red power wire. If your sensor has all the same-color wires, The first wire from the left is ground, then the two data pins, then power. When you plug in the power, you may see the LED blink to indicate the sensor is working. Since the sensor wires are so thin and short, we stripped the wire a bit and melted some solder on so it made better contact but you may want to solder the wires to header or similar if you're not getting good contact. Wire up the sensor as described in the sketch comments after uploading the sketch. put your setup code here, to run once:
#Sfg demo fingerprint serial
Allows Leonardo to pass serial data between fingerprint reader and Windows. To do this, you'll need to upload a 'blank sketch' this one works well for "traditional" Arduinos, like the Uno and the Mega: The easiest way to do this is to connect it directly to the USB/Serial converter in the Arduino. The interface/test software is unfortunately windows-only but you only need to use it once to enroll, to get the fingerprint you want stored in the module.įirst up, you'll want to connect the sensor to the computer via a USB-serial converter. The easiest way to enroll a new fingerprint is to use the Windows software.

You can enroll using the Windows software (easiest and neat because it shows you the photograph of the print) or with the Arduino sketch (good for when you don't have a Windows machine handy or for on-the-road enrolling). Once you've enrolled all your prints, you can easily 'search' the sensor, asking it to identify which ID (if any) is currently being photographed. First is you'll need to enroll fingerprints - that means assigning ID #'s to each print so you can query them later. There are basically two requirements for using the optical fingerprint sensor.

The library can enroll and search so its perfect for any project.
#Sfg demo fingerprint full
But, of course, we wouldn't leave you a datasheet and a "good luck!" - we wrote a full Arduino library so that you can get running in under 10 minutes. We like this particular sensor because not only is it easy to use, it also comes with fairly straight-forward Windows software that makes testing the module simple - you can even enroll using the software and see an image of the fingerprint on your computer screen.
