These have to be the least accurate things I have ever seen.
The rectangular one is accurate or accurate enough and has been what I used but I noticed files all had cutouts for these round hygrometers…
Well from my 6 pack 1 is within a margin of error to even be useful.
I get they aren’t expensive but seems like a waste of money for this bad.
@Krauerking@lemy.lol ALRIGHT. I just got all my sensors today. I’ll do a quick test with BME280s, 680s, and SHT41s later this week (Once I figure out that I’ve received all the sensors I wanted). I also got a few commercial Zigbee sensors for temp/humidity to compare against, just in case.
In either event, curious question for both y’all - did you calibrate/compensate your hygrometers with sealed container and table salt?
