What Is Data Logging?

Data logging is defined as the collection of data over a period of time or manual sampling taking accurate measurements using SI units. (The Vu data logger also has the option to measure in non-standard units for embarking learners).

Data logging systems monitor a process using sensors linked to a computer via a data logger – in this case the Vu logger.
Put simply:

  • Sensing is using sensors to show changes in the environment.
  • Monitoring is keeping a record of measurements from sensors over a length of time.
  • Data logging is the gathering, recording, classifying and presenting data in a variety of ways to help answer scientific questions

Working scientifically the Vu data Logger, accompanied by the EasySense software, can be used to:

  • Record findings
  • Display data in tables, charts and graphs
  • Allow for interpretation and analysis of data; recognising patterns and trends in the data
  • Enable presentation of results and conclusions which can be used to make predictions for new values, suggest improvements and raise further questions
