Hi,
We have 5 AS7331 sensors. 2 of them work perfectly with the example code whereas there are 3 others with issues:
- 1 sensor: stuck on AS7331 UV A/B/C Command (One-shot) mode Example
- 2 other sensors: Provide readings but keep the same value for UVC:1.30
Could these sensors be faulty?
Thanks!
Are you power-cycling/restarting the controlling software/hardware? Are you trying to use them all at once? How are they powered/wired?
They are connected and powered by an Arduino Uno in line with the default schematics on 3v3 for power. Restart/power-cycling doesn’t have any effect.
Are you trying to use them all at once?
Odd - can you share a photo of the setup?
Does changing the baud, reconnecting, or anything else change the behavior?
Will share a photo of the setup. Multiple things have been tried but no change for those sensores
