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.
| 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. |
