Want your own air quality monitoring station?

The GAIA air quality monitoring stations are using high-tech laser particle sensors to measure in real-time PM2.5 pollution, which is one of the most harmful air pollutants.

Very easy to set up, they only require a WIFI access point and a USB power supply. Once connected, air pollution levels are reported instantaneously and in real-time on our maps

About the Air Quality Levels

AQIAir Pollution LevelHealth ImplicationsCautionary Statement (for PM2.5)
0 - 50GoodAir quality is considered satisfactory, and air pollution poses little or no riskNone
51 -100ModerateAir 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.
101-150Unhealthy for Sensitive GroupsMembers 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.
151-200UnhealthyEveryone may begin to experience health effects; members of sensitive groups may experience more serious health effectsActive 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
201-300Very UnhealthyHealth 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.
