Wishiot Green Light Optical Fingerprint Reader Sensor Module for Arduino Mega2560 UNO R3

Note: If the code does not work , please change the arduino IDE to 1.6.6 Features: Make adding fingerprint detection and verification super simple. 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 can be stored in the onboard FLASH memory. There's a red LED in the lens that lights up during a photo so you know it is working. 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 False Accept Rate (FAR): <0.001% (security level 3) False Reject Rate (FRR): <1.0% (security level 3) Search time: <1.0 seconds (1: 500 average) PC interface: UART (TTL logic level) Baud rate (UART): (9600*N)bps (N=1~12, N default 6, equal 57600bps) Working environment: Temperature: -20 °C to 50 °C Relative Humidity: 40% RH to 85% RH (non-condensing) Storage Environment: Temperature: -40 °C to 85 °C Relative humidity: <85% H (no condensation) Lighting: Long light/Flashing Dimensions (L* W* H): 56*20*20.5mm 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:http://www.diymalls.com/files/FZ1035GFingerprintSensor.zip https://drive.google.com/open?id=0B8DSGdAr8_31Z3FrN0h0aHBpbXM Package includes: 1 x Green Light Fingerprint Recognition Module
