Nice video with good information. I'm going to order one to try. Thanks for your effort.

[@cad3175]

..very nice, thank you for sharing

[@RaadYacu]

Nice component pcbreflux. So even a fingerprint on a paper is readable by the machine?

[@pcbreflux]

Yes, but I am not sure how this effect the security of the module. You still need access to the original fingerprint ;)

[@pcbreflux]

Just a addition ... in my tests it seems not to work if you compare a real fingerprint and a black and white image. Works only if also the trained/enrolled fingerprint is also a printed picture. But this could be a color or slightly sizing issue. So be aware to change the factory password to prevent some kind of physical attack.

[@Huynh-Tan-Quoc]

you have library micropython for esp32?

[@abdulrasheed01]

Getting error when build on Arduino 1.8, install ESP32 library as well.
.enroll:1:28: error: SoftwareSerial.h: No such file or directory
Where is above said file please

it not detecting any fingerprint in my case.

In line 15 > FPM finger; < there is an error: no matching function for call to 'FPM::FPM()'
Can you help me with that?

how to send fingerprint ID to mysql database?

[@browaruspierogus2182]

I stopped using Arduino with ESP32 and instead use rtos idf. Everything is so much better and smoother now.

Hi! Can i know where can get your full coding ?

[@pcbreflux]

Nicholas 9395 Hi, thanks. Follow the github link in the description or you can also go to the main path github.com/pcbreflux/espressif and browse all examples. Have a nice day

[@niclee9716]

pcbreflux where can I get the coding for the fingerprint module send data to google sheet? With the ESP8266

[@ahostn]

How secure is this? Not much I think 🤔

[@pcbreflux]

There is some security to store the fingerprints (text calculation) in the chip with a pass-phrase and you can change it. But in general the security depends also on physical protection and how many level you implement (i.e. add also a PIN, NFC token, Bluetooth beacon, ...). And sure don't expect to much for ~$6.

[@iland2064]

i need full library ? i try error fatal error: SoftwareSerial.h: No such file or directory

[@pcbreflux]

Have you tried other libraries instead? AltSoftSerial or advancedSerial?

[@iland2064]

i uses library from github.com/brianrho/FPM but not work.. why?

@@iland2064 Hello men, I have a question. Did yo solve your probem with the library? I have a node MCU ESP12E and I'm trying to connect with the fingerprint sensor but I couldn't because exist an error.

[@M.4y]

how can i connect this to mqtt

[@pcbreflux]

On arduino you can implement several mqtt libraries for the esp32. Search for "github esp32 mqtt arduino". Don't be sure if there is a secure (mqtt via ssl/tls) version?

[@baiturjoss7290]

If I use esp8266. It is can.?

[@pcbreflux]

Don't test this, but this works also on much simpler MCU so the esp8266 should work with maybe slight changes (i.e. PIN mapping).

[@PinkuUsagispoonfork]

what is the pin 16 and 17 in nodemcu esp8266??

[@PinkuUsagispoonfork]

how to change the pin, for example i want to use pin d3 and d4 in nodemcu, should I change the code? which code? i m new in this think🙏🙏
