Comparing two vibration sensors

Our ME 633 team assembled a two sensor vibration setup and compared three channels recorded in LabVIEW. I took part in the assembly and contributed discussion and analysis of the recorded response and sensitivity.

My part in the project

I helped assemble the setup with the team and contributed the discussion and analysis. I compared how the two sensors responded to vibration and discussed the differences in sensitivity. The side by side traces make the response of each sensor easier to examine than a single peak value.

The Keyestudio sensor provided analog and digital outputs. The MiniSense provided the other sensor response. The signals here are recorded voltages, so the comparison is about the observed sensor output.
