Most irrigation controllers are clock-based timers, irrigating based on dates and times, indifferent to weather or plant needs. Imagine operating your air conditioning and heating based on dates and times only – with no thermostat. Not very effective. Smart irrigation timers monitor air temperature, rainfall, humidity and wind. They also consider the types of plants in each irrigation zone, the slope, exposure and type of sprinklers. Healthier plants and way less water.
