Learn how to record, store and analyse environmental data
You can use the BBC micro:bit V2 with built-in speaker as a data logger, recording data from its built-in sensors. Data is stored on your micro:bit even when its power source is disconnected.
What is data logging?
Data logging is the recording of data over time. It's used in school science experiments to record environmental or physical data. This might be for short bursts of time, for example measuring the acceleration of an object as it falls, or over longer periods of time, such as recording sound levels over a day or temperature or light levels over a week or more.
Why is it useful?
The micro:bit V2 is packed with environmental sensors for light, temperature, magnetism, acceleration and sound. You can record and store data from these sensors on your micro:bit, and retrieve them later for study.
The data stays on your micro:bit even when the power is disconnected, and no special software is needed to read it. You can examine your data in tables and a visual graph preview straight from the micro:bit just using a computer's web browser, and download the data to a spreadsheet so your students can analyse the data statistically, visualise and interpret it.
