Automated Systems

Sensors, microprocessors and actuators

  • An automated system is a combination of software and hardware (for example, sensors, microprocessors and actuators) that is designed and programmed to work automatically without the need of any human intervention.

  • Just like monitoring and control system mentioned in Chapter 3.

  • Application areas:

    • industrial

    • transport

    • agriculture

    • weather

    • gaming

    • lighting

    • science

Microprocessor and sensors for monitoring and controll system

  • Sensor sense data

  • Convert data through ADC

  • Store data in microprocessor

  • Microprocessor Compare data

  • Activate signal through DAC

  • Continue

Industrial applications: A nuclear power station

Industrial applications: Manufacture of paracetamol

Transport applications: Self-parking cars

Transport applications: Adaptive cruise control

Agriculture applications: Irrigation system

Weather applications: Station

Gaming applications

  • Gaming devices involve sensors to give a degree of realism to games:

    • accelerometers (these measure acceleration and deceleration and therefore measure and respond to tilting the gaming device forward/backward and side to side)

    • proximity sensors (used in smart touch pads; here electrodes are embedded in touch pads that can detect hand/finger position thus increasing user awareness).
