Using m5stickc plus2 to record environmental noise and send the dBA to a pushgateway endpoint.
This uses FFT to help calculate decibels and filters through a preset range of A-Weighted coefficients (what human ear can hear). Use the buttons to filter/calibrate the live capture to your decibel meter. Note the long press doesn't work so pressing the m5 button has to be one quick press and pause sadly.
