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.Yes they work well. No batteries needed. They give clear indication of dry/moist/soggy. I was over-watering and killing plants before I bought one.
