def log(t):
""" A function for logging data from an MS5803 sensor to file at a regular interval.
The function saves a line of text at each interval representing conductivity, temperature,
pressure. The device then goes into standby mode for interval t. After interval t, the
device awakes as if from a hard reset. The function is designed to be called from
main.py. Puts device in standby mode upon completion.
Parameters
----------
t: int
logging interval (seconds)
Example
-------
To log data at 30 second intervals, save the following two lines as main.py
>>> import logger_pres_temp as logger
>>> logger.log(30)
Note
----
For more robust logging, the lines related to the watchdog timer can be enabled
by removing the comments. However, once the watchdog timer is set, it will automatically
reset the board after the watchdog timer interval unless the timer is fed. This ensures
that the board will continue to log even if an error is encountered, but it can
cause unexpected results if the user wishes to interact with the board over serial.
