I have this sensor connected to a Breakout Garden on a Pi 0 with an official Pi power supply, and it provides very responsive readings but I don’t think that they’re quite accurate.
Attached is a graph with a small spike behind glass, and then a high spike for what was a bright, yet low-sun winter’s day. The UVB I reading was 9, which is hard to believe this time of year.
I’ve had a look around some boards, and others are reporting this issue too but I couldn’t find a work-around or calibration method.
Does anyone have a fix for this?
