    Why wouldn’t they? It just measures electrical resistance of the soil, less moisture means more resistance. Nice and simple.

    I have cheap one connected to arduino, and small water pump conected to it too. It works nicely.

      The soil composition, minerals and nutrients can change the eletrical resistance. Thats what i read somewhere.
