Saratoga-weather.org hosts a PurpleAir PA-II-SD air quality sensor on the north side of the house adjacent to the temperature/humidity sensors for our Davis Vantage Pro Plus weather station. The results are automatically sent to purpleair.com website for aggregation and analysis. The readings below are from both sensors in the PA-II-SD sensor unit.
Note: PM2.5 readings are native PurpleAir values and may indicate higher AQI readings when wood smoke is the predominant pollution.
