The Finger Print Sensor module is typically used in safes - there's a high powered DSP chip that
does the image rendering, calculation, feature-finding and searching. Connect to any
microcontroller or system with TTL serial, and send packets of data to take photos, detect prints,
hash and search. You can also enroll new fingers directly - up to 162 finger prints that can be
stored in the onboard FLASH memory. There's a red LED in the lens which will light up during
taking photos so that you know its working condition.

Plug the Grove - Base Shield into Arduino and connect Arduino to PC by using a USB cable.
When you plug in the power, you can see the red LED blink which indicates the sensor is working.

The library can enroll and search so it is perfect for any project. It can help you get running in under
10 minutes. There are basically two requirements for using the optical fingerprint sensor. First one,
you'll need to enroll fingerprints - which means assigning ID #'s to each print so you can query
them later. Once you've enrolled all your prints, you can easily 'search' the sensor, asking it to
identify which ID (if any) has currently been photographed.
