The Datalogger extension is an extension in the MakeCode Editor that allows sensor data to be recorded automatically over a longer period of time.
The data is saved in HTML format on the Calliope’s USB drive. It appears in tabular form and can be viewed directly, visualised as a plot or exported to Excel.
Prerequisites: Calliope mini 3, computer or iPad
A MakeCode programme with the extension imported can be downloaded here.
Around 10,000 timestamped measurement values can be stored.
The data can be displayed in parallel via the serial monitor in the browser.
The measurement frequency can be conveniently set using the “every 500 milliseconds” block.
Before implementation, it is worth planning:
What should be measured?
How often should measurements be taken?
How are the measurements started and stopped?
Further information on the extension’s code blocks can be found here.
