Data logging systems


Data logging systems


  • Data collection can be automatic so no human presence is necessary
  • Readings can be continually taken over long periods
  • There is no chance of somebody forgetting to take a reading
  • Readings will be more accurate if a computer takes them because there is no chance of human error
  • Sensors can be placed in locations where it is dangerous for humans to go
  • Readings can be taken very quickly [several readings every second from a number of different sensors]. Humans could not achieve this.


  • If there is a fault it may go unnoticed for a long time
