Data Logging & Control Systems

Data Logging & Control Systems

1. Data Logging

   • Advantages
     • more accurate
     • no one will forget a reading
   • Disadvantages
     • equipment can be expensive
     • could go wrong

2. Control Systems

   • Advantages
     • Robots can be put in dangerous situations- no health risk
     • Do not need to take breaks
   • Disadvantages
     • Assembly line jobs can be lost
     • Robots can be expensive to repair

3. PIR sensors are used to detect movement

4. Heat sensors are used to detect human body heat

5. Security Systems

   • PIR sensors can be used to detect movement
   • Heat sensors can be used to detect human body heat

6. Automatic Doors

   • Uses PIR to detect movement and opens doors when someone comes near

7. Traffic Control

   • Some traffic lights use traffic detection loops
     • Can detect when a car goes over that part of the road and turn the light green

8. Car Parking

   • Some cars use light sensors to sound a bell if you reverse too close to a wall
   • Some car parks can take a photograph of the cars license plate

9. Greenhouses

   • Heat sensors can tell actuators to open a window if it becomes too hot
     • Actuator = mechanical device operated by control systems

10. Simulation

    • Flight and car simulators use actuators to move the simulated cockpit when a joystick or wheel is moved

11. Robotics

    • PIR sensors in robots can detect movement to avoid human injury
    • Robots can spray cars
    • Robots can lift heavy objects
    • Robots can put together parts of machines
