The Arduino Fingerprint sensor makes adding fingerprint detection and verification to your project super simple.
- It contains 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.
- 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.
