A few months ago, my WS2812 (with the TX59UN-1-IT sensor) began acting weird.
I noticed that, when we had fog or rain situations, the humidity would read very low...like in the teens.
I reviewed several months of stored data (hourly), and found that below about 75% outdoor humidity... (checked against nearby airport reports)... my sensor seems to be "close enough". This included the "actual" dry conditions, where the real humidity was down in the 30s. (we rarely go below 30 around here).
But once the real humidity gets higher than 75 or thereabouts, my READINGS plummet into the 30s. As the humidity gets higher, the readings get lower: 20s, teens. In one dense fog situation where the airport said 98% (as expected), my reading was 8%. That's EIGHT.
It is almost as if the reading is:... 100 MINUS "actual-humidity".
Does anybody have the engineering explanation as to how the sensor can read "dry" in both "actual dry", and "actual wet" situations?
...And, of course, do you think there is any potential fix, (beyond the obvious, of replacement)? (And yes, clean the cobwebs, new batteries, etc.)
