SBK-CSV-File

Forewords

When recording the sensor data, the DataLogger do store the data into a CSV file.

Unlike a computer, the microcontroler that powers the DataLogger has no concept of regional settings.

Consequently, the commonly used settings are applied when generating the CSV files and write numeric values into them.

CSV convention

The comma is used as field separator.

Numbers are written with

• dot as decimal separator
• Without thousand separator

Text value are double quoted

DateTime are encoded with the format "dd/mm/yyyy hh:nn:ss"

• dd: day of the month in two positions
• mm: month of the year in two positions
• yyyy: year in four positions
• hh: hour in two positions (00 to 24)
• nn: minutes in two positions (00 to 59)
• ss: seconds in two positions (00 to 59)

CSV filename is based on its creation time:

• yyyymmdd-hhnnss.csv (see datetime encoding here above)
• stored into the /data path.

The capture below show a short example of CSV file generated by the datalogger.
