yeah, it’s usually 60% ambient humidity here, and then in the dry box it’ll read <15%. so that’s a pretty decent indicator to me that it’s working fine. I don’t really care if it’s 10, 15, or even your 25%, those are all way less than the ambient baseline and let me know that the dessicant is working.

If you’ve got some need to the humidity accuracy then that’s another thing, but for me that’s why I use those cheapos.

I use modified cereal containers with dessicant on the bottom and have a mount modelled up for those sensors.

because if it says anything other than 10% (the lowest thing it reads), then the dessicant needs to be refreshed.

it’s more of a binary output rather than trying to look at 53 vs 55%
