Hey!
I'm having a question about the Adafruit fingerprint sensor. Well, actually I'm not sure if it's the adafruit sensor because i bought it from my local electronics store and it had no information about where it came from. Apart from some other models mine blinks a green light and has mysterious 6 wires (only 4 are used in the Adafruit sensor documentation). I was pretty sure these 2 other wires were just useless until I stumbled upon this sensor.
It has exactly the same color variations for the wires and the 2 excess wires are marked as SEN1 and SEN2 there. They're supposedly used for proximity sensors, which would be really useful in my case. However I have found no documentation about these sensors and hence came here to ask if anyone has any experience with them.
Looking forward for your anwers,
Kaarel
P.S. Overall, the sensor is working brilliantly and I set it up using the Adafruit documentation
