In a simple IoT diagram, the garden light is classified as an _____?

The idea being tested is how devices in an IoT diagram differ in function: sensing versus acting. A garden light is the actuator because it performs a physical action—emitting light—based on a control signal from the system. It doesn’t measure or sense anything itself, so it isn’t a sensor, and it isn’t the decision-maker deciding what to do—that role lies with the controller. In simple terms, sensors gather data, controllers decide what to do with that data, and actuators carry out the resulting action. Since the garden light produces light in response to a command, it fits the role of an actuator.
