PaulS:
The problem is that when i add a clock module to my project, it stops logging when the log-file is about 100 kb (although the memory card is 2 Gb).
Does it stop logging, or does it simply take longer to log the data?
Why not create a new file before the old one gets that big? One file per day, or week, or month, or whatever.
Is the temperature really changing that much? Logging once every 5 minutes is probably good enough, isn't it?
Thank you both for reply..
It simply stops logging. I connected LED to indicate the pauses between recordings. LED works SD-card recoring doesnt.
Last time i started the logger in the evening and in the morning i noticed that it had stopped 3.00 AM.
Logging frequency was about 1 recording in 5 min.
