minus-square@monobot@lemmy.mllinkfedilink3•1 year agoWhy 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.
minus-square@LuckyBoy@lemmy.worldlinkfedilink1•1 year agoThe soil composition, minerals and nutrients can change the eletrical resistance. Thats what i read somewhere.
minus-square@mertn@lemmy.worldlinkfedilink3•1 year agoYes 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.
Do they really work?
