Abstract
A weather based irrigation controller has a thermometer that provides a temperature signal to the controller and a rain gauge that provides a rainfall signal to the controller, for adjusting irrigation schedules. A default mode is initiated when either sensor fails, and introduces an adjustment to the maximum irrigation duration based on historical stored data.
