Abstract
An irrigation control device (12) with a controller (14), antenna (16), power supply (70) and battery charging device (72), such as a solar array, all contained within a housing, such as a rotor body (90). The controller (14) receives signals through the antenna (16). The controller (14) updates one or more watering schedules stored in a memory module (32), based on the received signals, and generates control signals to execute a watering schedule. The battery charging device (72) recharges the power supply (70) and the irrigation control device requires no external electrical connections for power or control. Control signals are generated in a central controller (18) remote from the rotor (12), and are preferably transmitted to the rotor antenna (16) through a commercial paging or other type of public broadcast network (20, 22, 24).
