Accelerometer & Gyroscope
Accelerometer & Gyroscope
Add-on Module
About
The Accelerometer & Gyroscope add-on module allows 24/7 collection of accelerometer & gyroscope data from compatible Garmin devices.
Accelerometer
Accelerometer measures acceleration along 3 orthogonal axes (x, y and z).
Accelerometer data is recorded at 25Hz which equals 25 measurements per second. This will result in 2.16 Mio. measurements per person per day.
If enabled, accelerometer data is continuously recorded by the Garmin device. Its frequency or recording interval cannot be influenced or configured.
Data export includes the starting timestamp for each second only. All other measurement points need to be calculated based on the 25Hz interval.
The unit of measurement for accelerometer is milli-G’s.
The range of x, y, z values would theoretically be -/+31998 milli-G’s.
Accelerometer data generates approx. 562.5KB/hour.
Fraction in the data export refers to the fraction of the measurement within each second. It represents the milliseconds from the timestamp.
Fluctuations in recording frequency may occur and are normal due to error tolerances of the hardware. This will also vary between devices and models.
Gyroscope
Gyroscope measures angular velocity along 3 orthogonal axes x, y and z.
Gyroscope data is recorded at 32Hz which equals 32 measurements per second. This will result in 2.76 Mio. measurements per person per day.
If enabled, gyroscope data is continuously recorded by the Garmin device. Its frequency or recording interval cannot be influenced or configured.
Gyroscope data is exported as array of x,y,z values.
Data export includes the starting timestamp for each second only. All other measurement points need to be calculated based on the 32Hz interval.
The unit of measurement for gyroscope is degrees/second.
The range of x, y, z values for gyroscope would theoretically be -/+1146.81 deg/s.
Gyroscope data generates approx. 562.5KB/hour.
Fluctuations in recording frequency may occur and are normal due to error tolerances of the hardware. This will also vary between devices and models.
