Having trouble finding the right piece of hardware

I'm currently attempting to make a fully automated system where whenever the humidity level hits relatively low levels, it would trigger a piece of hardware I'm missing (prolly a fogger/mist maker I don't know of), to fetch water from a water deposit and use the water to spray it's surroundings (or use the water to create a damp enviorment, such as a mild fog), subsequently increasing humidity levels.
If anyone can recommend me a piece of hardware that would do the job, I'd really appreciate the help.
(apologies for any grammatical errors of any sort, as my keyboard sucks and english is not my arterial language)
