Re: Re: Moisture sensor
Getting back to moisture sensors - I wonder what is inside those
cheapo
"spike" types with the meter on ? Anyone broken one open ? How
accurate
does this application need to be (especially as it could rain torrentially
immediately after automatic watering if met forecasts are not integrated) ?
Cheers,
David
