SEN55 PM1,2.5,4,10 values reporting out of range

[drcrockerjr]

Describe the bug When running the SEN55 sensor the values reported for the PM 1,2.5,4, and 10 are occuring outside of the defined 0-1000 range defined in the datasheet.

Hardware in Use WheatherChimes/ Whisp

To Reproduce Steps to reproduce the behavior:

1. Upload code provided below for sunning the SEN55 sensor
2. Place flame or smoke source near SEN55 sensor air inlet
3. Observer PM values outside of 0-1000 range

Expected behavior The PM values should be between 0-1000

  // Log the data to the SD
  hypnos.logToSD();

  // Pass in the batchSD to the mqtt obj to check/ publish a batch of data if ready
  mqtt.publish(batchSD);
  //mqtt.publish();

  // Set the interrupt duration for 5 minutes
  hypnos.setInterruptDuration(TimeSpan(0,0,5,0));

  // Reattach the interrupt
  hypnos.reattachRTCInterrupt();

  // Set the hypnos to sleep, but with power still being supplied to the 5v rail (wait for serial when testing from a computer)
  hypnos.sleep(false, true, false);

  hypnos.networkTimeUpdate();
  //manager.pause(2000);
}

Output Copy and paste the serial output here if possible wrapped in ``` ```

Additional context Add any other context about the problem here.

Can you additionally post the serial output?

[drcrockerjr]

I lost the output in my serial monitor. It is only on the SD card of the unit at this point. I can add it after I am able to get a new Whisp up and running as im currently testing the Whisp i used when i encountered that error.

Closing as this appeared to be an improper use case
