Abstract:
1. An irrigation control device comprising: a coil configured to develop an electromagnetic flux sufficient to cause actuation of irrigation equipment; control circuitry coupled to the coil and configured to receive, at input connections, control signals comprising a modulated power signal from an external irrigation control unit of an irrigation control system and configured to control the electromagnetic flux at the coil based on the control signals, wherein the control circuitry is configured to derive data from the modulated power signal and based on the data, output signaling to the coil to cause the coil to develop the flux; and a housing covering at least a portion of both the coil and the control circuitry, the housing including a threaded end configured to thread the irrigation control device to a valve assembly to be actuated by the electromagnetic flux of the coil, the housing having a first wall generally extending around the coil and at least in part generally corresponding to a curvature of the coil, and a radially expanded portion extending around the control circuitry, the control circuitry being positioned in the radially expanded portion of the housing, the coil being positioned in part in the expanded portion of the housing and being electrically connected to the control circuitry in the expanded portion of the housing; wherein the control circuitry is further configured to communicate to the external irrigation control unit via the input connections.
