R302 Fingerprint sensor finger detection

Hi guys,
I have bought an R302 fingerprint sensor to connect with my NodeMCU.
It works correctly and I’m able to read/write finger correctly.
From documentation I see that the sensor has a finger detection power+signal.


I would like to use that to wake up my NodeMCU from deepsleep but I don’t know how this finger detection pin should be connected to my board.
Could you please give me some hint? :confused:
Thanks :smiley:
