Measure the air you breathe

A simple cheap device is available to measure air quality - 
A) CO2 = Carbon dioxide, fresh air is 350 to 450 ppm.
1000 to 2000 ppm indicates poor air quality and causes drowsiness.
Current measurement at Hawai'i is 414 ppm.

B) HCHO = Formaldehyde, maximum recommended exposure is 0.100 mg/m3

C) TVOC = Total volatile organic compounds, maximum recommended is 0.250 mg/m3

D) Temperature 

E) Humidity

You can see that inside my home the air quality is as good as the outdoor air.
