  • Working on it. Waiting for some packages.

    The rectangular ones are slightly more reliable from personal experience but likely just as possible to be low quality. From working with them the design layout leaves less space to get obvious flaws such as the RH sensor being installed facing the board which seems to be true for most of the round ones, they also have a separate and dedicated temp sensor unlike the round ones and use a double battery setup since voltage can also affect the accuracy of the reading.

    But the RH sensor between the units seem to be identical as is the inability to calibrate.

    Personally the paper strips are very reliable if just looking for a binary answer of if it’s gotten past a threshold and are incredibly cheap.

    Abe recommended an electronic daughter board sensor that was cheap but requires skills I don’t have.

    And I have found medical grade ones that can be purchased cheap “used” as they are often single use for shipping purposes to make sure the item was kept in specific conditions. But that brings me back to waiting for the. To arrive and test.


    TL;DR

    These cheap electric square or circle ones are both luck based with some preference to the square. But cheap paper humidity sensors can be gotten if you just want to toss them in a bag to make sure they haven’t gotten water damaged as a binary identifier.

    For reliable accuracy look elsewhere.






  • Yeah Samsung. So that is something we agree on.

    The case is weird I don’t want to buy a bulky one on Scamazon that pops free from the glue being cheap like the second case I tried to buy. So that is where I am at not being able to find them. I got gifted a case from Debrand and it literally wouldn’t let the phone fold enough to trigger the sensor to turn off the interior screen.

    Seems pixel is better, but I liked the Microsoft duo for being wider but that died hard.

    They just don’t feel like a permanent answer from the cell phone manufacturers.
    But I’m glad they found a home with someone that gets the most out of it. Everyone has got unique needs I feel these are still just hyper specific.


  • Yeah, that seems good enough for most people and I agree with using it instead of wasting the money on these even for a secondary check. I just wanted to track a new desiccant that doesn’t indicate and see how it compares to cheap silica.

    The old school probably would work better in that they are often adjustable or calibratable, and I feel like I’d trust them more than these to even accurately change with added humidity. I’m gonna end up using paper Testors cause those honestly seem the more reliable analog system.


  • Fair enough. I guess my point is that since they swing between them so much how do you know you didn’t put a sensor in there that is reading way under humidity and is actually closer to 40% while reading 15?
    I guess it doesn’t really matter if it’s just to see if the humidity appears to be increasing over time but that difference between them makes me worry I won’t catch if it’s actually matching humidity because of a difference between the readouts.

    I’m also a very OCD nerd about certain things so, that’s not helping me with these. I feel I can’t compare any one of them against another for much purpose but only use them singularly at best for humidity change trend if I’m actively tracking it.

    Say outside is reading higher than actual and inside is reading under actual and you might miss them being technically the same. I also just got non indicating desiccant so that’s another reason I kinda care.


  • Neat. My signal is worse, my phone collects dust inside the hinge and I have had to replace so many screen protectors as well as deal with the fact that the front screen is narrower and thus makes typing on it worse and creates typos now a lot. And I still can’t get a phone case for the life of me or it.

    I prefer the fingerprint sensor not being under the screen for sure but that was solvable without needing it to fold.

    I’m glad you are finding a use case but as someone that also remotes into PCs I actually just prefer to pull out a laptop. And I hate how the software often doesn’t work seemlessly between open and close causing apps to restart and lose progress.

    That’s just my findings though. Didn’t want previous commentor to feel alone among others praising it when I have found issues as well. We are all basing our feelings on these off emotions anyways. That makes it a gimmick in my eyes.


  • DampRid? Wait I already have calcium chloride then.

    Ok well I guess I can test if they even scale right but I’m not holding my breath around them, I’m not sure the extra humidity I breath out anyways would register on these.

    I really think I might just take the batteries from these and call it a loss and use better components.

    Thank you for the testing info! Actually really helpful.



  • So, just because my rectangular one has been with me for a few years I’m gonna stick up for it a little. It does have 2 sensors in it separated for temp and humidity compared to the circular ones that seem to have the temp sensor baked into the board if it exists at all and the humidity sensor was poorly soldered upside down. But agreed on likely carelessness of assembly from identical parts.

    Same batteries and sensor modules it seems and even the press fit nature of them. And the only reason I know that specific one I’m reading against is accurate is because I only kept it because it was the accurate one from a pack of them I grabbed from a lab in college.

    I just don’t get why everyone uses them is my point if we are in agreement they kinda suck.





  • Lucky. Pretty sure these are the same from the same internet source but the swing on them is insane. They all showed as 75% in the bags but spending some time with them I realized the complete lack of accuracy when I realized my humidity wasn’t what it was reading.

    I have since taken some apart and cleaned them out but now those are just under the humidity by the same percent they were over before.
