#103061 - soil dampness
Responding to: ???'s previous message
Erik,
I have seen some systems that dont sense the soil at all
but instead use a small container that collects rain
and a float switch. when it rains enough to trigger the float
switch (approx 1 inch) it disables the sprinklers until
the water has evaporated from the container. The idea is
that a small amount of rain will not disable the system,
and a large amount will not re-enable it until things have dried out.
