I would like to ask you for suggestion. I would like to monitor vibration of the motor in my system. What should I use MEMS microphone or 3-axis  Accelerometer  or Both? I am using stepper motor to  drive a pump and I would like to monitor the behavior of entire assembly. I have found an latest reference design STEVAL-IDP005V1 which contain both 

 IIS2DH ( 3-axis Accelerometer ) and MP34DT05 ( mems microphone ). Could you explain me why on the reference design are both sensors and is there any specific software which based on the sensor input notify system about specific behavior? 


Thanks a lot in advnace
