How do you convert IIS3DWB accelerometer data to vibration values? Is there an algorithm that has to be part of the c code?

Is IIS3DWB data already vibration information, or is there some algorithm needed to convert to vibration data? https://www.st.com/en/mems-and-sensors/iis3dwb.html

[TDK · Accepted solution]

Vibrometers and accelerometers both measure acceleration. No conversion is necessary.

Thanks TDK. How do people chart out frequency vs g? Trying to see how to get the frequency component. I have heard of people doing FFT, but, not sure how that works.

FFT can be used to show frequency information. There is a wealth of information available if you search for it.

Thanks TDK, as you can see there is some conversion work that has to be done on accelerometer data to get vibration information .... I will look into c implementation

Suppose that depends what you mean by vibration information. Clearly, if you want the FFT, you need to perform the FFT.
