Mold detection

Hi all.
I live in a fairly humid area, in quite an old house. In winter we often have some issues with rising damp / mould inside some infrequently used cupboards.

Other than temp / humidity sensors, is there any hardware device that can detect such a thing?

Thanks

Any of the plant moisture sensors should do if you can get them to contact the damp area sufficiently.

Not Hardware, but may help

I’m thinking I might get some more temp / humidity sensors for the relevant spots

I am working on the same issue.
Things I am have tried:
Control exhaust fans based on humidity:

Added little dehumidifiers in some rooms.
I was actually looking into getting some “Sky Plants” today. In fact here is the link I had open when I saw this:

I am actively working on this and trying new things out but having data helps:
