Additional Info

STEVAL-STWINKT1B sensing equipment can be subject to a very wide range of low frequency (imbalance or misalignment), medium frequency (worn gears or bearings), and high frequency (worn cooling fan bearings) vibrations, which is why our node carries several high-performance accelerometers, IMUs, and magnetometers, capable of detecting movement along 9 axes to a very high degree of sensitivity. For very high frequencies in the order of tens of kHz, vibration analysis is covered by sound and ultrasound applications based on data coming from a digital microphone and a high-performance analog microphone, respectively.
