Problem with A01NYUB sensor - ask for help
r.marciniak84 2020-04-15 23:48:25 2036 Views2 Replies Hello,
I just bought A01NYUB and connected it to my RPi4B. I have downloaded library from https://github.com/DFRobot/DFRobot_RaspberryPi_A02YYUW. The issue I face is that I get only 3 reads of sensors at the beginning and most of the time no data. Moreover if I play with sensor I get error from script.
Please notice that I use only sensor and RPi4B, no additional board. I have modified DFRobot_RaspberryPi_A02YYUW.py as it was created for sensor with smaller range(450 vs 750). I only modified the min/max values.
See below:
