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.
I've been through all the junk Amazon hygrometers, name brands, no name, all junk. How has your experience been with the inkbird ITH10? I hope abe writes up a walkthrough for the DHT11/22 and ESP8266/32 setup, it'd be neat to order from Ali and work something up.
Just bought them after the realization of this. I will try to make sure I let you know as I found a really good deal that I'd be happy to share as well if they are good as long as you are fine with used.
cheers mate
So I got my inkbird ITH10s and they are at least for me what I was looking for.
They aren't all perfect and have a slight variation between them but they are consistent and only cost me $14 for 6 of them. And I'm really only trying to get a rough idea of difference between enclosure types.
But yeah these do feel consistently like e-waste that for most people's need of tracking if their humidity on their filament has gone too high that the answer is just the color changing paper readers. That or old mechanical ones that are always on in a simpler way.
I've tried the old spring one's too, and the spring quality determines the accuracy, but again, not over time. Turns out the Inkbirds are equally as accurate as the Protmex showed, all the TermoPro's were junk, and after a brief chat with ThermoPro customer service they refunded my entire purchased which was over 6 months ago, so that was nice. I think my body has been conditioned by bad Hygrometers to misjudge waht 40% rh should feel like, but the inkbirds were a good find, am gonna keep the protmex to do spotchecks on the inkbirds every nowa and again
