Inputs Sensors capture analog data, such as temperature, pressure, light. This is
converted to digital by a AD (analog-to-digital) converter, so that it can be
processed by a computer.
Processing The microcontroller or CPU makes a decision on the basis of the data input.
If some threshold is reached, then some action is taken.
Output The system affects the outside world in some way, e.g. turning on a heater,
moving a robot arm, adjusting the speed of a motor. The generic term for
the mechanism by which a control system acts on its environment is an
actuator.

Examples Automatic doors
• Heating systems
• Taxi meters
• Elevators
• Washing machines
Process control • Device drivers
• Domestic robots • GPS systems
• Traffic lights
Automatic doors Inputs
Optical motion sensors emit infrared or microwave radiation and detect it
rebounding off an approaching person. The amount of radiation detected is
converted to a digital value by an AD converter.
Processing
• If the value corresponding to the amount of radiation reflected back into
the sensor exceeds some pre-set threshold, a command is issued by the
microcontroller to open the doors.
Outputs
• Motors attached either to a hydraulic arm, belt or cable pull or slide the
doors open. After some pre-set delay, the doors close again.
