The Finger Print Sensor is one optical fingerprint sensor which will make fingerprint detection and verification adding super simple.There’s a high powered DSP chip AS601 that does the image rendering, calculation, feature-finding and searching. 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 which will light up during taking photos so that you know its working condition. It is easy to use and by far the best fingerprint sensor you can get.

The Finger Print Sensor module is 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 that can be stored in the onboard FLASH memory. There’s a red LED in the lens which will light up during taking photos so that you know its working condition.
The library can enroll and search so its perfect for any project. It can help you get running in under 10 minutes. There are basically two requirements for using the optical fingerprint sensor. First one, you’ll need to enroll fingerprints – that means assigning ID #’s to each print so you can query them later. Once you’ve enrolled all your prints, you can easily ‘search’ the sensor, asking it to identify which ID (if any) has currently been photographed.
Open the enroll code directly by the path: File -> Example ->FingerPrint->Enroll.
Upload the code into Arduino.
Start up Serial Tool and Select the ComNum and BuadRate used by the Arduino.
Select the “SendNew” option. Send the ID # you want to use. You can use up to 162 ID numbers. And it will ask you to press the finger to the sensor. At the moment, you should see the red LED blink.
If your press is OK, you could see the following message. You will then have to repeat the process, to get a second clean print. Use the same finger! On success you will get notice.
If there’s a problem such as a bad print or image, you’ll have to do it again.
Once you have the finger enrolled, it’s a good idea to do a quick test to make sure it can be found in the database.
Open the demo code:fingerprint and upload it.
When prompted, press a different/same finger to the sensor. If it is the same finger, you should get a match with the ID # as show below.
If it is not a finger in the database, This serial port will output nothing.
