In the same diagram, what type of device is the moisture detector?

In IoT, devices are categorized by function: sensors, actuators, and controllers. A moisture detector measures moisture and outputs a signal that reflects that condition, which is exactly what a sensor does—detect and report environmental data. It doesn’t perform an action itself (that would be an actuator) and it doesn’t process or make decisions (that would be a controller). So the moisture detector is best described as a sensor, even if it’s used alongside a controller and actuator in a complete irrigation system.
