|or let us find your nearest air quality monitoring station|
The GAIA air quality monitor uses laser particle sensors to measure PM2.5 and PM10 particle pollution in real-time.
Very easy to set up, it only requires a WIFI access point and a USB power supply. Once connected, air pollution levels are reported instantaneously and in real time on our maps.
It comes fully equipped with water-proof cables, mounting tools, power supply and an optional solar panel.
This station is part of a sensor network. In order to ensure the highest level of data quality, the signal to noise ratio (SNR), defined as the coefficient of variation from the hourly readings, should be relatively low (below 33%). Any measurement with SNR constantly higher than 10% could be biased because of incorrect sensor readings (such as defective fan or dust accumulation).

|AQI||Air Pollution Level||Health Implications||Cautionary Statement (for PM2.5)|
|0 - 50||Good||Air quality is considered satisfactory, and air pollution poses little or no risk||None|
|51 -100||Moderate||Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.||Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.|
|101-150||Unhealthy for Sensitive Groups||Members of sensitive groups may experience health effects. The general public is not likely to be affected.||Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.|
|151-200||Unhealthy||Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects||Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion|
|201-300||Very Unhealthy||Health warnings of emergency conditions. The entire population is more likely to be affected.||Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.|
|300+||Hazardous||Health alert: everyone may experience more serious health effects||Everyone should avoid all outdoor exertion|
