Weather Underground’s Next Frontier: Air Quality

OK, I see where my test was wrong
it was using an existing data file

the local IP data is currently used for all the data
the sensor ID method (from the cloud data) is used to get the channel 2 PM2.5 data (in case the channel 1 data from the local IP data is out of range)
do you not have the local IP data working correctly maybe?

what I can do is set the cloud data (via the sensor number) to get the 1.0 and 10.0 data if that is not available via the local IP data
yes?

Correct–I don’t have the IP method working. I get an error message when I enter the IP and press the Test button. (See the message attached.) Only the sensor ID method is working for me. Sure, you can get the 1.0 and 10.0 data using the could method if you can. However, I only see the 2.5 data in the cloud data but maybe I overlooked it.

the local IP needs /json
on the end
(like the example when you first setup it up)
(and you may or may not need http:// at the start)

Success! The 1.0 and 10.0 values now work when I enter the IP as http://192.168.1.165/json. (I did have to add http:// along with /json on the end.)

Now if you could make the AQI value retain its position on the main screen, I will be happy and won’t bug you anymore about this!

have done that with the latest .zip update

I have added some max/min/av data now in the latest update

also the AQI number now has a font with a shadow so when yellow colour its easier to read

I have added more to the av/ext data in the latest .zip update now

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

fixed in the latest .zip update

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.

I have added some more custom tags (max/min average etc) to the latest .zip update

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.

I have added more custom tags for use with your purple air sensor now to the latest .zip update
(see the tagslist.txt file)
i,e average monthly values

Could anyone help me find my sensor ID?
Sensor name on PurpleAir map: Pleasant Grove
Location NE Kansas

Thanks!

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.
