In the diagram, what type of devices are the power supplies?

Power supplies act as energy sources for the circuit. In an IoT diagram, sensors are the devices that detect physical quantities, actuators are the ones that perform actions in the environment, and controllers (the processing or control logic) decide what the system should do based on input. The power supply’s job is simply to convert and deliver the required voltage and current to run these components; it does not sense data, perform actions, or make decisions. Because of that, it doesn’t fit as a sensor, an actuator, or a control element, so the appropriate label is none of the above. If you see a symbol for a voltage source or power adapter in the diagram, that’s indicating the energy source rather than a functional device like sensing, acting, or controlling.
