Update on PMS5003 Calibrations

Our cloud averages the data points into 5 minute averages. This is probably the difference from your script.

You are correct that we are piling through a lot of data right now bit it looks very good with our approach. I believe next week we will roll out some features that will make it easier to correct the Plantowers.

I just noticed that @Siriel_AirGradient’s new algorithm showed up on my unit as part of that OTA update I did not realize I got. :stuck_out_tongue: I’ll start monitoring for when I get updates now.

@Achim_AirGradient Would this be the most optimal set of settings since I know my sensor is from that batch? Or is using the EPA one stacked on top not recommended?

  "corrections": {
    "pm02": {
      "correctionAlgorithm": "slr_PMS5003_20240104",
      "slr": {
        "intercept": 0,
        "scalingFactor": 0.02896,
        "useEpa2021": true
      }
    }
  }
}

Yes, the EPA should be used on top. Your setting looks correct.
