You’ve downloaded a CSV data file and you’re wondering what each column stands for (please also refer to "Technical description of Hexoskin data channels" in the Articles Section):
1st column: Timestamp
Hexoskin samples some of its data at 256Hz so timestamps found in the CSV file is in 256ths of a second since 12:00 am 1st January 1970 GMT+000. If you want a regular Unix timestamp, simply divide the value in the first column by 256.
Each line represents a second in time. To get raw data at 1/256ths of a second, please use our API.
2nd column: Breathing Rate (breaths/minute)
This is the number of breaths per minute, calculated as the average breathing rate of the last 7 breaths.
3rd column: Heart Rate (beats/minute)
This is the heart rate in beats per minute.
4th column: Minute Ventilation (ml/minute)
This is the number of milliliters (ml) of air breathed in per minute
5th column: Cadence (steps/minute)
This is the number of steps per minute, relevant only when the activity involves walking or running.
6th column: Activity (g)
Basically, we get a square root of the sum of the square of each of the accelerometer components.
