Let me know when you have that sprinkler control system running. With all the travel I do, I could use that. I think you are right about the response time on the camera, but look at moisture sensors. Water the lawn at, say, 03:00, see if it is still moist during the course of the day, and vary the water time accordingly. Don't forget to offset for trees and bushes adjacent to the zone. Moisture sensors will also help offset rain. -- The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized. -- U.S. Const.
