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 Hygrometers are only as good as their components. Buying a DHT11/22 or SHT31 from AliExpress ($1-2) alongside an ESP8266/32 and you’d have much better results than buying these “are my cigars dry” pucks.

I’ve had massive differences in readouts in DHT22 from aliexpress. They are really not good sometimes

@callcc@lemmy.world SHT31/41 are better than DHT22 tbf. DHT would have a variance of about 2-5%. It also takes a while for it to stabilize.

Thanks for the tip. The BME280 are also not too bad.

I’d really love to know how, once having purchased and aquired these two parts, how to join them, and get them powered, and to display. this is like secret engineering knowledge i’d love to be walked through

@shoulderoforion@fedia.io I have about $150 worth of Ali parts and components coming just this month for whole house monitoring for this kinda thing - temp, humidity, CO2, VOCs, pressure, light sensors etc. Would be glad to ping y’all once that writeup is done :)

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.

I don’t even think these would helpfully let you know if your cigars are dry. 2 of them barely changed humidity over time and I noticed the sensors were flush with the board instead of exposed.

I ended up buying inkbird ITH10s because I generally don’t go completely self made since I’m not overly tech crafty and more work with my hands crafty.
