20080288116Automatically Adjusting Irrigation Controller - Methods and devices are provided to automatically determine plant water requirements and adjust irrigation in order to make efficient use of water. In one implementation, an irrigation control unit comprises a memory storing historical values of a plurality of variables used at least in part in calculating plant water requirements, and at least one input adapted to receive signals corresponding to current values of one or more of the plurality of variables. The unit also comprises a processor coupled to the at least one input and the memory, the processor adapted to determine the plant water requirements at least in part using, for each of the plurality of variables, a current value in the event the current value is available and at least in part using, for each of the plurality of variables, a stored historical value in the event the current value is not available.11-20-2008
20080288117Modular and Expandable Irrigation Controller - Described herein are several embodiments relating to modular irrigation controllers. In many implementations, the irrigation controllers are modular in that various functional components of the irrigation controller are implemented in removable modules that when inserted into position within the controller, expand the capabilities of the controller. Also described are various different types of expansion modules that may be coupled to the modular controller, having as variety of functions and features, as well as related methods of use and configuration of these modules in the controller. In some embodiments, authentication procedures are provided for one or both of a modular irrigation controller and an expansion module to determine if they are authorized to operate together.11-20-2008
