Purple Air Channels. **solved**

[grwkak]

Just learned I can add my Purpleair sensor to my stations.

After doing so, I see the following in the live data:

3 Air
3 Air #1
3 Air #2
3 Air #3
3 Air # 4
3 Air #5

I have the dual sensor version of the Flex.
I am assuming Air and Air 3 are 10 micron measurements, Air 1 and 4 are 2.5 micron and Air 2 and 5 are 1 micron.
Does this seem reasonable. Snapshot of data:

The Flex Purple Air has two chanels A and B. The correspondence is below:

3 Air PM10 (Chanel A)
3 Air #1 PM2.5 (Chanel A)
3 Air #2 PM1 (Chanel A)
3 Air #3 PM10 (Chanel B)
3 Air #4 PM2.5 (Chanel B)
3 Air #5 PM1 (Chanel B)
Measurements of PM1 and PM10 particles are estimated, i.e. based on PM2.5 values.
This is due to the fact that due to the scarcity of heavier particles, the sampling time required for correct PM10 measurements is longer than 5 minutes , while PM2.5 is sampled every second!

Many thanks!
