ABSTRACT:
A rain sensor for use with an irrigation control system includes a position sensing element. A moisture absorptive element is supported for receiving rainfall. An actuating element is mechanically connected to the moisture absorptive element for movement adjacent the position sensing element as the moisture absorptive element expands and contracts to thereby induce a change in the position sensing element that can be used to generate an interrupt signal without any mechanical connection between the moisture absorptive element and the position sensing element.
