It has only equivalent carbon dioxide (eCO2) with metal oxide (MOX) levels

** Installation
It requires [[https://platformio.org/ ][platformio ]] and =gnu make= , obviously.
#+NAME : build
#+BEGIN_SRC sh :eval never
make # or `make build`
#+END_SRC
#+NAME : flash the firmware

In the event of TVOC issues, inspections should be carried out to find
the root cause of the problem and address it as exposure to the VOCs
may harm health. Indoor VOC levels up to 350 ppb are
acceptable. However they should not exceed 500ppb. –
450 to 2000 ppm (parts per million).

*** Particulate matter
+ PM1 :: are extremely fine particulates with a diameter of fewer than 1 microns.
+ PM2.5 :: (also known as fine particles) have a diameter of less than 2.5 microns.
+ PM10 :: means the particles have a diameter less than 10 microns, or 100 times smaller than a millimeter.
** TODO
In gneral I want the stack to be pluggable as much as possible. The current scope of wanted readings is not including any plans on it's implementations.
