Any ideas? - Thanks
System log files won't show anything for processes started by cron. Unless specifically redirected all their output and error messages are discarded.

If a reading once a minute is acceptable you may wish to convert your script from a loop with a 30 second sleep (don't forget a fixed duration sleep will actually have an interval of "time it takes to do stuff" + 30 seconds so readings will not be every 30 seconds) to a one shot with no loop and call it once a minute from cron.
If you opt for a systemd service instead of cron it can be configured to restart a failed service automatically.
