o Is it useful to measure O2 in open spaces? It tends to vary very
o Which sensors are solid state and which use consumables or have
short life spans?

a list of sensors used by the Air Quality Board of California for
freeway fume monitoring, and a list of sensors the EPA uses for
natural disasters, like 911. The initial list of chemicals to be
where for this I know sensors cost between 20 to 40 dollars for
low sensitivity, ppm range. For ppb range, sensors go up in price
between 50 to 200. It's not for everyone, but it would be good to
have a few of each in neighborhood.
There are also the smog measurements, both the initial smog
chemicals measured by California, which included non visible
molecules, which were removed from the list measured. Also, high
altitude smog components known to be even more toxic are not
Also, jet fuel fumes for near airports. And for the prevailing
downwind direction from factory sections of town, we should add
toluene, acetone, alcohol, and other VOC's, cleaners, known to be
in use at those facilities.
Asbestos is a more difficult one, and should be rotated to those
stations downwind of building being demolished.
So, creating Google map zones, or our own OpenGIS website, listing
sources (based on government and private industry web published
lists) and their prevailing "plume" direction and size, for
recommending types of sensors in/under the plume, as well as
displaying real time results.
I know a self funding method after we have several stations in
I'm all for regular monthly meetings, for face to face, design and
implement and test meetings.
It would would be good to become a certified calibration lab in
the awesome state of California, so we do not have to go Weights
and Measures department labs, and pay their fee rates.
BTW, these sensors come with boards that are Arduino compatible!!!
Or the raw sensor can be hooked directly to the Arduino.
Better, is bulk buying likely can cut the price down.
