Niko, thank you for providing the link to the ‘Worldwide Air Quality’ site - quite interesting, very informative. Just wish my dexterity, my sight and my brain cells were a bit younger … I would certainly get involved into building my own air quality sensor… :oops:
Brian, the ID found in the ‘airquality.txt’ data file is not the sensor ID. To view the data uploaded by my PurpleAir unit to the Thingspeak cloud storage, use the following link:
https://map.purpleair.org/json?show=1256
Using the above link in a browser will display a JSON data file. Using the above link as the IP Address in the software ‘cronairquality.exe’ will download the JSON data file (and overwrite the previously saved data file).
