Tip 22: Irrigation Smart Controllers

What is a smart controller? A smart controller is just that "smart." Based on readings taken from a sensor or information sent to the controller, a smart controller decides where, when and how much water your irrigation system puts out. For the most part, it takes the human 'guessing factor' out of the equation and does exactly what an irrigation system is supposed to do...supplement natural rainfall along with taking into account soil types and evaporation.
