  • An automated system is a computer-controlled setup where sensors, microprocessors, actuators, and networks work together to collect data, make decisions, and control devices without constant human input.
  • Types of automated systems:
    • Sensors: detect and collect data from the environment like temperature, motion, light, and proximity (e.g. security alarms, automatic lights, parking assist).
    • Controllers/microprocessors: process input from sensors and run programs/ algorithms to send commands to actuators.
    • Actuators: carry out physical actions based on commands (e.g. moving robot arms, heating boilers, speakers, and alarms).
    • Communication networks: allow different components to exchange information, either through wired connection (e.g. Ethernet, USB) or wireless connection (e.g. Wi-Fi, Bluetooth). This may include internet access for remote monitoring.
    • Human–machine interface (HMI): the way users interact with the system (e.g. touchscreens, buttons, mobile apps, and dashboards).
