flashtree FPM12 Optical Fingerprint Reader Sensor Module for Arduino Mega2560 UNO R3

Specifications: Supply voltage: DC 3.8-7.0V Operating Current: <65mA Peak current: <95mA Fingerprint image time: <1.0 seconds Window area: 14.5*19.4 mm Signature File: 256 bytes Template files: 512 bytes Storage capacity: 1000 Note: There are basically two requirements for using the optical fingerprint sensor. First is you'll need to enroll fingerprints - that 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) is currently being photographed. You can enroll by 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) Connection pin #2 is IN from sensor (GREEN wire) pin #3 is OUT from arduino (WHITE wire) 5V connect sensor (Red wire) GND connect sensor (Black wire) Document link: Package includes: 1 x Fingerprint Recognition Module
