LSM6DSO RMS values

[gabriel.arnautu]

Hi,

I am using a LSM6DSO accelerometer. I want to know what type of acceleration I am getting as output: RMS acceleration or just the acceleration amplitude?

Regards,

Gabriel

Hi Gabriel, you get the amplitude data (that can be positive or negative, while the rms value is only positive by definition). You can calculate the rms value in post-processing

Hi Eleon,

Do you have any idea what are the steps that I have to perform in order to get the rms value from amplitude?

​Hi Gabriel, you need more than one samples to calculate a RMS value (at least two consecutive samples. You can follow this link for the formula:
