Fascinating Fact:

Data logging is used in science experiments, weather stations, fitness trackers, and smart homes to monitor conditions.

In KS3 ICT, data logging means using sensors and a computer or data logger to collect readings over time. You can choose how often data is recorded, then store it and analyse it using tables, graphs, and patterns.

Key Terms

Dataset: A collection of recorded values, such as a list of temperatures measured every minute.
Trend: A general direction shown by data over time, like a steady rise or a repeating cycle.
Real-time monitoring: Watching data as it is collected, so you can react immediately if something changes.

Frequently Asked Questions (Click to see answers)

What is data logging used for?

Data logging is used to record measurements over time, such as temperature, light, sound, or movement, so people can spot patterns and make decisions using the results.

How does a data logger work in ICT?

A data logger collects signals from sensors, converts them into digital data, and saves the readings with times or intervals. The data can then be displayed as charts or analysed on a computer.

What is the difference between real-time monitoring and data logging?

Real-time monitoring shows readings as they happen, which is useful for quick action. Data logging stores readings over a period so you can analyse changes and compare results later.
