this sketch will allow you to bypass the Atmega chip // and connect the fingerprint sensor directly to the USB/Serial // chip converter. After the wiring over upload the following sketch to Arduino board. Put red & black in (+5V & GND) respectively. To use this sensor with ComputerĬonnect the white wire from the sensor to Arduino D0 pin and green wire to Arduino D1 pin. These two steps makes microcontroller / System to authenticate right fingerprint. The fingerprint identification process has two steps that is Thanks to the Adafruit here we have Fingerprint library so that connect this sensor to Arduino as well. The DSP processor has on board FLASH memory which can store 120 finger prints. you need GUI software called SFGdemo or SYNOdemo download the software. You should see the following, with a blue success message and some device statistics in the bottom corner. Now you need to connect the fingerprint sensor module. Start up the SFGDemo software and click Open Device from the bottom left corner. Download the SFGDemoV2.0.rar file and unzip to a destination of your choice.

It provides TTL serial out hence we can connect to any microcontroller or system. The SFG Demo software is a simple, free program that connects your PC to the Fingerprint ID module. This optical fingerprint reader devices uses high powered DSP chip AS601 form Synochip, that does the image rendering, calculation, feature finding and searching. To add fingerprint verification in microcontroller projects we can use this all in one optical fingerprint sensor-scanner (R305), It makes fingerprint detection and verification super simple.īy using this sensor we can make Bio-metric authentication and access control based Electronic projects easily. By using this we can make pretty sure about security needs. The Fingerprint is one of the safest way to detect and identify the Authorized person, We know that fingerprint is unique even identical twins do not have identical fingerprints.
