I use an Adafruit fingerprint sensor at work to check when people come to work and when people leave from work.
I’ve got some complains that it takes time/ doesn’t work as fast as people would hope.
It takes about 1 second (if it works) to read the fingerprint and around 1 second to match it in a table and send it to the system.
I want to speed this up and make it a bit more reliable but I’m not really sure where to start. Since the documentation is in Chinese. Should I just run it all on a much faster µC or is there any documentation so I can optimize it? The serial communication is set to 57600 baud but I don’t think that’s the limiting factor.
Normally I like to write my own code for handling communication but the documentation for the fingerprint sensor is in Chinese and when translated it becomes very hard to read.
My goal is to just rest your finger on the sensor while walking and barely stopping. The current system is using RFID and it’s really fast but my coworkers keep forgetting there RFID tags at home so I’ve got to make a better solution
Any information would help!
