Year 10 - Design and technology

Data logging

Systems approach to design: Sustainable Futures

Unit Summary

Pupils will develop knowledge of electronic components and a systems approach to designing. They will learn about different components and use these to build and test circuits for different purposes. They will design a system to control a greenhouse environment, considering the different variables.

Lesson Summary

You will learn to design a control system to log data over time.

Key Notes

  • Data is a piece of information which can be stored and used by a computer program. This could be numbers or words.
  • Different types of data can be collected from a control system, such as temperature, light levels or moisture levels.
  • A variable is a piece of data stored in a computer's memory which can be accessed and changed.
  • Data logging is a collection of data over time.
  • Feedback is a signal that is sent back in a loop, depending upon a condition.

Vocabulary To Learn

  • data: a piece of information which can be stored and used by a computer program
  • variable: a piece of data stored in a computer's memory which can be accessed and changed
