摘要： An irrigation system includes an irrigation controller, at least one environmental sensor and a vandal resistant data relay. The irrigation controller includes a two conductor hard wired communications link for accepting an actual value of at least one parameter of interest from an environmental sensor in the form of data encoded on the conductors via current modulation. The environmental sensor is mounted in a location remote from the irrigation controller. A circuit is connected to the environmental sensor for transmitting an RF signal representing an actual value of a parameter of interest detected by the environmental sensor. The vandal resistant data relay is connected to the two conductor hard wired communication link of the irrigation controller. The vandal resistant data relay includes a receiver that receives the RF signal, and circuitry configured to extract the actual value of the parameter of interest and emulate a predetermined set of physical and protocol properties of the two conductor hard wired communication link of the irrigation controller.

摘要： A modular irrigation controller includes a processor capable of executing a stored watering program and controlling a plurality of removable station modules in accordance with the watering program. Each station module includes a station module circuit for opening and closing a plurality of valves. A plurality of connectors can mate each mate to establish a communications link between the station modules and the processor. A plurality of terminals are each connectable with a corresponding one of a plurality of field valve lines from the valves. The terminals are mounted separate from the station modules and are connected to the connectors. This allows the irrigation controller to have a more compact design, provides connection terminals for spare field valve lines, and eliminates malfunctions due to erroneous re-connection of field valve lines during station module replacement.

摘要： An evapotranspiration (ET) unit includes a first communication link, a processor and a second communication link. The first communication link receives actual ET data from a plurality of environmental sensors. The processor calculates changes to a set of watering schedules of a predetermined watering program of a separate irrigation controller based on the actual ET data. The changes can increase or decrease the frequency and/or length of ON times for selected stations. The second communication link transmits the changes to the irrigation controller.

摘要： A processor is connected by a bus to a plurality of station modules, each station module being connected to a corresponding valve and having a micro-controller. The processor executes a stored watering program and controls the station modules in accordance with the program. Messages are bi-directionally sent and received over the bus that are generated by the processor and the micro-controllers. Each message contains an identification field with an instruction that describes a meaning of the message. The processor and the micro-controllers each interpret the messages received thereby and perform predetermined functions in response thereto.

摘要： An improved irrigation controller is provided for selectively turning ON and OFF each of a plurality of sprinkler valve stations around a lawn or garden. The controller permits direct entry on a station-by-station level of the run time, number of cycles, and frequency of operation. The controller then permits both start time and no water days to be entered globally.
