Using data loggers to collect data

Data logging

Unit Summary

In this unit, pupils will consider how and why data is collected. They will explore how sensors monitor the environment. Pupils will collect data as well as access data captured over long periods. They will look at data points, data sets, logging intervals and use a computer to analyse data.

Lesson Summary

You will learn to explain that a data logger collects data points from sensors over time.

Key Notes

  • A data logger is a digital device that can automatically record data from sensors over a period of time.
  • Data loggers take readings at set intervals (e.g., every 1 second, 5 minutes, or 1 hour).
  • The timing of these intervals affects how detailed the collected data will be.
  • Shorter intervals give more detailed data, but require more storage.
  • Using this data, you can identify and explain patterns shown in the data.

Vocabulary To Learn

  • logging: capturing and displaying or storing data points (usually over time)
  • data point: a discrete piece of data, often part of a data set
  • interval: the time between data readings

Common Mistakes To Avoid

  • Shorter intervals give less detailed data.

3 Quick Questions (With Answers)

1. Describe the system or process from this lesson in clear steps.

A data logger is a digital device that can automatically record data from sensors over a period of time. Data loggers take readings at set intervals (e.g., every 1 second, 5 minutes, or 1 hour).

2. Define this computing term and give one practical example. 'logging'

capturing and displaying or storing data points (usually over time). Add one real device or system example to prove understanding.

3. Correct this common computing misconception.

Mistake: Shorter intervals give less detailed data. Correction: If you were to take your temperature every minute, you would have more detailed data than if you took your temperature every hour because there would be more readings.
