Abstract
Methods and systems control an irrigation system that includes an irrigation controller, a valve actuator, and at least one irrigation sensor connected by a communication circuit. A sensor charging pulse having a temporal duration less than a solenoid actuation time threshold for a solenoid is provided over the communication circuit. The sensor charging pulse charges a charge storage device in at least one irrigation sensor. A series of addressing pulses is also generated over the communication circuit, which indicate a device identifier of at least one irrigation sensor. The series of addressing pulses activate at least one irrigation sensor having the device identifier indicated by the series of addressing pulses such that the activated irrigation sensor provides a sensor signal indicative of an irrigation condition to the irrigation controller via the communication network.
