Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. These modules are 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 1000 finger prints can be stored in the onboard FLASH memory. There's a green LED in the lens that lights up during a photo so you know its working.


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. But, of course, we wouldn't leave you a datasheet and a "good luck!" - we wrote a full for library so that you can get running in under 10 minutes. The library can enroll and search so its perfect for any project. We've also written a detailed tutorial on wiring and use. This is by far the best fingerprint sensor you can get.


Usage is very simple : as long as there are serial microcontroller , embedded modules can operate this , MSP430, 51, AVR, PIC, ARM, FPGA,Raspberry Pi , for controller so you can operate this module . This module is controlled through the serial port , you can use the computer's serial port to control this module.

Products from optical fingerprint sensor , high-speed DSP processors , high-performance fingerprint matching algorithms, such as large -capacity FLASH chip hardware and software composition. The fingerprint module is stable, functional, both fingerprint , a variety of functions fingerprint registration , fingerprint matching , fingerprint search.
