minus-squaremertn@lemmy.worldlinkfedilinkarrow-up3·7 months 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.
minus-squaremonobot@lemmy.mllinkfedilinkarrow-up3·7 months 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-squareLuckyBoy@lemmy.worldlinkfedilinkarrow-up1·7 months agoThe soil composition, minerals and nutrients can change the eletrical resistance. Thats what i read somewhere.
Do they really work?
