Hi,
I am using adafruit fingerprint sensor and It seems to be reading confidence level 272 or 336 or 241 at different instances . I read it on this link: https://learn.adafruit.com/adafruit-opt ... th-arduino that the range is between 0-255. Can you please let me know what is the false value. Also if there is a chnage in the confidence level, how many data points will change in the signature. I also checked the signatures and there seems to be many differences every time I tried to read the same finger.
Here is the signature the first time:
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
and then the second time:

Re: Fingerprint sensor confidence level
Also what is the confidence level above which the fingerprint sensor determines that a fingerprint is a match?
