This is the output of a portable air particulate monitor. (It is mounted in a tackle box and runs for over 5 hours on batteries.) Using my cellphone for internet connectivity, it is a completely self-contained monitor that transmits data up to the website as long as it has power. The unit can run and charge itself from a car cigarette lighter outlet.
Each reading from a Dylos DC1100 instrument is averaged over five minutes and the graphs are updated every thirty minutes. Large particles (above 2.5 μm) are shown in red while small particles (down to 0.5 μm) are shown in orange. Wind conditions and humidity are collected simultaneously from the weather station at the coordinates 44.89°N 91.86°W. The north (green) and west (blue) wind components are recorded separately and are calculated to provide a true vector average. (For details, see the second method cited at http://www.ndbc.noaa.gov/wndav.shtml.)
