What type of device is the water valve? (sơ đồ)

The key idea is that a valve in an automation system is a device that performs motion to change flow. In IoT setups, sensors monitor conditions (like pressure or flow) and report data, while a controller decides what to do and sends a command. The component that actually moves to open or close the valve is the actuator, because it converts an electrical, pneumatic, or hydraulic signal into physical movement. So the water valve is an actuator. Sensors don’t move things, and a controller doesn’t directly actuate the valve without an actuator. Some valves may have sensing built in, but the part that changes the flow is the actuator.
