          CS244 – Lecture 7
         Sensors, Actuators and Other 
         hardware components
                         Winter 2010- CS 244            2
    Simplified Block Diagram
                                               actuators
                                               actuators
  ICS212 WQ05 (Dutt)  Hardware Components: 
       Sensors, Actuators, Converters
 Sensors and Actuators
    Sensors:
       Capture physical stimulus (e.g., 
         heat, light, sound, pressure, 
         magnetism, or other mechanical 
         motion)
       Typical generate a proportional                           mic
         electrical current                     solenoid
       May require analog interface                                        speaker
    Actuators
       Convert a command to a physical         laser diode/transistor
         stimulus (e.g., heat, light, sound,                               compass
         pressure, magnetism, or other 
         mechanical motion)
       May require analog interface
                                                  dc motor         accelerometer
    Sensors
   Processing of physical data starts with capturing this 
     data.
   Sensors can be designed for virtually every physical 
     stimulus
        heat, light, sound, weight, velocity, acceleration, electrical 
        current, voltage, pressure, ...
   Many physical effects used for constructing sensors.
        law of induction (generation of voltages in an electric field),
        light-electric effects.
       Example: Acceleration 
       Sensor
    MEMS device
    Small mass in 
        center
    When accelerated:
          Mass displaced from 
            center
          Resistance of wires 
            connected to mass 
            change
          Detect change in 
            resistance and model 
            acceleration
