An irrigation system includes an irrigation controller with an adjust feature and at least one sensor. The irrigation system further includes a sensor control unit operatively connected to the irrigation controller and the at least one sensor. The sensor control unit is configured to calculate an irrigation value using a signal from the sensor and to automatically modify a watering schedule of the irrigation controller through the adjust feature based on the irrigation value to thereby conserve water while maintaining plant health.

Systems and methods to adjust irrigation

An irrigation system includes at least one environmental sensor, such as a solar radiation sensor that is installed on an irrigation site, and a soil moisture sensor that is also installed on the irrigation site. Programming allows an estimated ET value to be calculated based at least in part on the output signal of the environmental sensor. A pre-programmed watering schedule is automatically modified based on the estimated ET value to thereby conserve water while maintaining the health of plants on the irrigation site. The system automatically inhibits irrigation when an output signal of the soil moisture sensor indicates an amount of moisture in the soil is above a predetermined threshold.

Irrigation system with ET based seasonal watering adjustment and soil moisture sensor shutoff

An irrigation controller has a control panel including a display and a plurality of user inputs. A processor is operatively connected to the control panel and to a memory. A plurality of switches are operatively connected to the processor for turning a power signal ON and OFF to a plurality of valves that deliver water to a plurality of sprinklers in different zones. Programming is stored in the memory for implementing a seasonal adjustment feature that is independently operable with a plurality of individual watering programs to selectively energize the valves. The programming calculates a soil moisture requirement value for each program using a signal from at least one soil moisture sensor that is associated with a zone that is assigned to that watering program, and automatically modifies the watering program assigned to that zone through the seasonal adjust feature based on the soil moisture requirement value.
