Fascinating Fact:

Accuracy depends on sensor quality and calibration, and poor calibration can produce misleading results.

In KS3 ICT, data logging means using sensors and a data logger to record measurements automatically, often at regular intervals. This is useful for tracking changes, spotting patterns, and turning readings into graphs or reports.

Key Terms

Data logger: A device or system that records data automatically, usually from sensors, and stores it for later analysis.
Sensor: A component that detects a physical change, such as temperature or light, and converts it into data a computer can record.
Sampling interval: The time gap between each reading, such as taking a measurement every second or every minute.

Frequently Asked Questions (Click to see answers)

What is data logging in KS3 ICT?

In KS3 ICT, data logging is when a computer system uses sensors to record measurements automatically over time, storing the readings so they can be analysed and graphed.

What is the difference between data logging and data capture?

Data logging records readings automatically at set times, often using sensors. Data capture is a wider idea that includes manual entry or scanning, where a person may input the data.

Why does the sampling interval matter in data logging?

The sampling interval matters because it affects detail and accuracy. If readings are too far apart you might miss changes, but very frequent readings can create huge files and noise.
