  1. Hi I have a question
    I am using asm330lhh gyroscope

The sensor is great but I see some kind of low frequency behavior in the data from this sensor

My ODR is 6667 range is 500

The accuracy is good, but this low frequency behavior will eventually cause problems for my work

Please help me...

Did I ignore something?!!

    Approximately what is the frequency of the interference? Wouldn't it be possible to use some band pass or high pass filter?

    Its frequency is very low, it will be removed by filtering, and of course it is not just one frequency, it is different on some gyros.

    I don't know whether this behavior is mechanical and vibration or software, I don't have any special vibration on the gyro body
