Data logging & Control systems

Data logging & Control systems

1. Data Logging

   • Advantages
     • Data logging is more accurate and no one will forget a reading
   • Disadvantages
     • The equipment can be expensive and coule go wrong

2. Control systems

   • Advantages
     • Robots can be put in dangerous situations and do not need to take breaks
   • Disadvantages
     • Assembly line jobs can be lost and robots can be expensive to repair

3. Security systems

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

4. Automatic doors

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

5. Car parking

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

6. Greenhouses

   • Heat sensors can tell actuators (mechanical devices operated by control systems) to open a window if it becomes too hot.

7. Robotics

   • PIR sensors in robots (programmable machines that perform a sequence of actions) can detect movement to avoid human injury. Robots can also spray cars, lift heavy objects, put together parts of machines and travel along track around a warehouse
