Moisture sensors won't work. They're designed for wet soil or air (i.e.
dew or rain).
Why don't you use a humidity sensor? After all, your wood chips or
whatever interact with the air around them, so there should be some sort
of correlation (might depend on ambient humidity and temperature, needs
to be calibrated even if you disregard that, but might work well
enough).
I have no idea how moisture of wood is usually measured -- heat the
stuff to 110 degC and weigh how much lighter it is afterwards?
If you tell us, we might get a better idea.
