Arduino and data

I have an Arduino and a Dust sensor PPD42 connected to it.

I read the data with PLX-DAQ

In the PLX-DAQ page there is 3 columns. The first is: lowpulseoccupancy with big numbers like between 20000to 200000 The second is: ratio with numbers like 0 to 0.11 and finally a third column concentration with numbers between 0.92 and 111

All those numbers vary in proportion of the dust i have nearby the dust sensor.

I would like to know the meaning of these data. Wich column represent the ppm of dust in the air ?


Thanks for helping.

    We can't help you with programming problems with the Arduino and we can't help you with a sensor not provided by Parallax. If you provide a link to a datasheet for a sensor, we can give you advice and suggestions. PLX-DAQ just receives data in the form of text and enters it into an Excel worksheet for display later.
