About this project

This Audio MFE neural network model detects anomalous sound originating from the HVAC system cooling fans:

  • normal
  • defective

After building my neural network model, I deployed my model as a fully optimized and customizable Arduino library and uploaded it to XIAO ESP32C6. Therefore, the device is capable of detecting anomalous sound emanating from the cooling fans by running the neural network model onboard without any additional procedures or latency.
