Fingerprint Optical Sensor Module for Arduino


The Fingerprint Optical Sensor Module for Arduino is one of the best ways to detect and identify the Authorized person(s). It is a well known fact that fingerprint is unique even identical twins do not have identical fingerprints. By using this you can make pretty sure about security needs. It makes fingerprint detection and verification super simple.

The Fingerprint Optical Sensor Module for Arduino reader devices uses high powered DSP chip, that does the image rendering, calculation, feature finding and searching. It provides TTL serial out hence we can connect to any microcontroller or system. The DSP processor has on board FLASH memory which can store 300 finger prints. Thanks to the Adafruit here we have Fingerprint library so that connect this sensor to Arduino.
