The script "particulateConcentration" acquires data from a public
ThingSpeak channel located at the MathWorks Headquarters in Natick, MA, and uses it to calculate an Air Quality Index (AQI). ThingSpeak (https://thingspeak.com ) is a cloud platform for collecting and analyzing IoT data with MATLAB.

The channel ID and read API key are already part of the code. Please note that in order to display this data on your own channel, add the channel ID and write API key. Enter the channel ID as a number and the channel key as a character array. Visit the link below for more information about the function:

The script "airHealth" uses the Air Quality Index (AQI) calculated in "particulateConcentration" to display the appropriate text associated with the index.
Please note that in order to display the appropriate text, enter the channel ID and read API key of the channel used in "particulateConcentration". Visit the link below for more information about the function:
