Brian, I've noticed that if the AQI is a value from 50.00 through 50.99, the description tag %purpleairaqidescription% is blank.

Using ZIP update Version on 16 September 2017 - 22:47:30.

Refreshing the topic. I had installed a home-made air quality sensor using the sensor from Sharp (GP2Y1010AU0F/GP2Y1010AU0F posted in this forum) and a MQ131 sensor (for ozone). I've been logging for a while now but don't get any exciting result. I do readouts either every 1 second or do a 10-sec average and log to a file.

I've noticed a difference between two sensors: GP2Y1010AU0F has an offset of about 0.4-0.5 V which is what the specifications say. The GP2Y1010AU0F has no offset (or 0.04-0.05 V).
I've attached a log for one day from both sensors that are installed side by side.

Either our air is that clean or something does not work OK. Can someone post a log for one day from the PurpleAir sensor? I wonder if the dynamics is more interesting there.
PS: I made a smoke from a candle and both sensors reacted immediately. So they should be connected alright. ??

Thanks.

Smoke is a good test. You may want to check the sensitivity specifications for those sensors to calibrate your expectations for general air quality sensing.

With the Napa wildfires, I have to say that the Purple Air sensor was a good investment.  The air quality around here has really sucked the last several days.

Purpleair sensor installed up here in norway.
Thanks a lot to all people involved and to Brian for integrating this in weather display.

Just to be sure:
  • Pleasant Grove, Kansas
  • Lat: 38.864466
  • Lon: -95.26798
If those coordinates are right then the PurpleAir sensor ID should 4415

Is there a graph for the purple air (see attached) that I can add to my site? I do not see any files/gifs being created by WD.
