BMX055 interference

[MiguelSanches]

Dear all,

I have acquired some BMX055 Bosch IMU's to test in a sensor that I am currently developing. However, I have some interferences/noise that I wasn't expecting when performing sensor's fusion.

When acquiring signals from an HX711 ADC the sensors baseline only has noise corresponding to the LSB variations of the ADC. However, when connecting the BMX055, the baseline from HX711 presents noise with much greater amplitude and well defined spectral density of approximately 19Hz.

Has this problem been reported before? What is the best filter to remove such interferences/noise?

Thanks in advance,

Miguel Sanches
