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.

    LOL same. And this is why I bought bad tech. It’s a whole wild world if you can actually take electronic components and just wire them together and program them yourself.

      You might just end up spending all your time doing that, though.

      Good times.

      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.

          ThermoPro TP39 and Inkbird ITH-10 After this thread the other day I bought some Inkbird’s on sale from Amazon to test them out, have had some ThermoPro TP39 around (and outside) of the house, and one of the Inkbirds was about 5% above on a salt test in a bag, out of the bag, they are all, seemingly reading LOW. Little sick of this, so I bought a Protmex HT607 to test out to see if my feeling is right, that the only one of the hygrometers in the photo that’s near correct (3%+/-) is the center ThermoPro. If my feeling is right, I’m going to return all the Inkbirds, and give ThermoPro some shit, make a warranty claim, where I’m sure they’ll send me 3 more junk hygormeters. I’m not prepared to spend $800 on a scientific hygrometer that can only do push button spot readings, can continue to be amazed that the market hasn’t produced an ADJUSTABLE always on moisture/humidity monitor. It’s pretty maddening.

            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
