How to make or salvage a humidistat and have it control a device? Answered
I'm using a portable plug-in electric kettle as a humidifier. This is it:
I have a separate little handheld hygrometer, so when I see that my room has reached a good humidity level I have to manually turn off the kettle.
My question is, what is the cheapest way to make a humidistat, even from parts salvaged from other things, and have it control this? I have experience in electronics, circuitry, soldering etc. but I don't know where to begin on this one. I can provide any info such as specs on the kettle if needed. Appreciate any ideas and thoughts!
