Maximum SamplingRate for Accelerometers and Gyroscopes

[DLetourneau]

Hello,

There is some information on the Sensor Guide here :

https://dev.fitbit.com/guides/sensors/accelerometer/#overview

https://dev.fitbit.com/guides/sensors/gyroscope/#collecting-readings-from-the-gyroscope

However, maximum sampling rate is not specified.  What is the maximum sampling rate of the accelerometers and gyroscopes ?

Thanks!

Maximum sampling frequency is 100Hz for accelerometer. I believe gyro can go up to 200Hz. We need to add this in the documentation and provide better examples. Thanks for pointing this out!

I was not able to sample higher than about 10 hertz.

I am not sure if the limitation is on the Fitbit side for the Ionic (or a mistake I am making in code) but I have not been able to consistently sample anything higher than 10 hertz at a regular interval or 14 hertz at an irregular interval. The documentation for sensor data does not seem to relate any of these physical/software/os/some other layer limitations.

I am going to assume that the max acceleration of those sensors is a lie.
