Crawl Space questions

what are people doing with their crawl spaces?
I cheaped out and put some cheap YoLink sensors in my crawl space last year but I was rudely awoken the other night where my crawl space was 80% humidity but as I freaked out thinking there was a leak I then realized the humidity level outside was 88%

So I’m thinking I need to spend the money to get a decent sensor that connects to smartthings and then do some comparisons such as the crawl space humidity is greater than 65% and Outside humidity is not greater than 70% or something.

also when looking at some sensors I saw there was some “Mold Detection” messages on Aeotecs web site was curious if thats a real thing

curious if I’m overthinking this and what others are doing?

to be clear my crawl space has fans that kick on if humidity is higher than 65% and it has vents all around the 1956 foundation that are open unless the weather gets super cold in texas where I will manual close them off with their covers and turn the fans off.

thanks
John

The Aeotec “mold detector” is a marketing rebrand of the regular humidity sensor, which has an alert based on the temperature and the humidity. So it’s really telling you the potential for mold, but not the actual presence of mold.

Mold Detector contains 3 sensors.
.

  • Humidity: +/- 3 % on relative humidity, +/-1 % hysteresis
  • Temperature: 0 … 65 °C +/- 1 Kelvin
  • Dew Point: 0 … 65 °C +/- 1 Kelvin (calculated from other sensor values)

Note that even the engineering spec lies to some extent because it’s calculating the dewpoint, not measuring it with a separate sensor.

Well, I guess I shouldn’t say “lies.“ it’s not completely untrue, but it’s something you probably already have, you just aren’t using it that way. :man_shrugging:t2:
