A soil moisture measuring device to tell when plants need watering. 2 for $10 on amazon.

    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.
