The module performs series of functions like fingerprint enrollment, image processing, fingerprint matching, searching and template storage.There is a high powered DSP chip in the module that does the image rendering, calculation, feature-finding and searching.This module can be connected to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash and search.This module can be used to enroll new fingers directly and up to 162 finger prints can be stored in the on board FLASH memory.There is a red or green LED in the lens that lights up only during a scanning process.

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 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 its working.
