This has to be invented and I just don’t know about it but if it isn’t it’s a non brainer to extra $$$”s. A “Smart Sprinkler” would shut off when rain is occurring and would work based on the actual moisture level in the ground. Therefore water usage would go down when it wasn’t needed and increase when it truly was of need. It could be adjusted as well based on the fullness that you want your grass and plants to achieve. Now it’s time for some brilliant scientists to work with me and make this dream a reality…. if it doesn’t exist already.
