“A smart irrigation controller internal block diagram with weather, rain, soil-moisture and flow sensors; a mobile app; an irrigation controller; a pump; a zone valve manifold; and garden zones. All sensors and the app connect to the controller; the controller commands the pump and valves; the pump feeds the valve manifold, which feeds the garden zones, with the zones returning soil and flow measurements.”
Read the decisions behind it.
Combines weather, rain, soil and flow feedback.
Separates pump control from zone-valve control.
Shows the mobile app as an external controller interface.
Use this view when defining smart-irrigation parts, feedback paths and external interfaces.

Common questions
Why use both soil and flow sensors?
Soil sensors measure watering need, while flow data can reveal delivery problems or leaks.
What does the valve manifold do?
It directs water from the pump to individual irrigation zones.
Can a mobile app be part of an internal block diagram?
Yes. It is shown as an external interface that sends configuration and manual-control commands.
