Hello, I am completely new to all of this so forgive me if my terminology is incorrect. I wanted to know if it's possible to activate a 12v relay using the input from a sensor. Specifically, I would like to turn on a relay (for 3 seconds every ten minutes) that activates a ceramic diffuser when the reading from a humidity sensor is below 68%. If the humidity is above 70% I do not want the diffuser being activated. Is this a complicated thing to do as far as coding it(is that the proper term?)
This is a set up I would like to build for an inwall cigar humidor that's automatically controlled.
The diffuser I'm looking at is in the following link.

The relay is a simple one like this:

And the humidity sensor I saw is:
