Polution and Noise level Questions


#1

I am using the sck in a project to control room temperature using a combination of window, fan, and aircon. The sck will be outside and I will read outstide temp, pollution , and noise to decide whether to open window, turn on fan, and /or turn on aircon. I have the following questions:

I see the pollution readings are:
“co":112.03,“no2”:21.46
Any ides which is better to use as a “simple” pollution index? CO or NO2? Any idea what number would be a good variable to decide to shut the window and turn on the air con?

I see the noise readings are:
“noise”:6
Is this always a single digit number? I would love for it to always be the same number of digits (xx.x) for easier transfer to my code.
Any idea what would be a good number for outside noise to decide to shut the window and turn on the air con instead (what is “loud”?

Thanks,
Drew

Just thought I would bump this.
