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

 

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)
