    BMI160 - Noise

    Hi,

    I wounder if  the BMI 160 can be effected by acoustic noise, from for example being mounted to close to a electric motor that is spinning with a high frequency.

    I Guess that is a possibility since its a MEMS Gyro.

    Have anyone seen this before?

    I can confirm BMI160 output could be affected by acoustic noise.   It depends on the frequency of the noise.

    And some noise may even damage the sensor when hit the resonance frequency of sensor units.

    The frequency around 20 - 30KHz and its harmonic frequency will also cause the problem.
