Logging temperatur and ground moisture

I can not give you a definitive yes @user95697, as I do not have experience with Micro:bit

Guess here: As long as power is not interrupted, and you don't run out of memory while data logging, I don't see why not.

I would wait for confirmation from others that do have practical experience.


EDIT: On p.6 of the 'dendrite' tutorial link provided in #1 heading 'Download and run the program' although a bit vague, it does state:

'(you can disconnect the USB and do this with battery power)'

then

'Reconnect the micro:bit to the computer via the USB'

It's not clear to me how the data is stored. Appears to be a string of text appended to an existing string. So that tutorial implies yes you can.

Example how text data is sent to a Micro:bit
