When you are in the market for a sprinkler controller, you will oftentimes see the world “smart” tossed around quite a bit. In the world of technology, “smart” is essentially referring to the intelligence of the system and sometimes to artificial intelligence. In this case, when you see a smart irrigation controller, it merely means that these are the models that will tailor the watering schedules to the needs of the specific landscape. These systems will use data information from weather sources, as discussed previously, to improve the efficiency of the watering. Plus, with smart designs, very little additional monitoring is going to be required on your part.
