#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. Bruce |
