The GAIA A18 is an improved GAIA A12 design, with solar panel power and long-distance radio, allowing the station to operate in areas where either power supply or WiFi connectivity is unavailable.
The GAIA A18 can operate using the battery for seven days without a recharge. The solar panel battery can recharge the battery within a few hours under direct sun conditions. Using both the solar panel and the battery, it is possible to operate the station forever off-grid, provided you have at least one sunny day every week.
The GAIA A18 can operate using WIFI like the GAIA A12. But it also comes with "long-range" connectivity support (LoRA), allowing you to locate your station several hundreds of meters up to several kilometres from your network gateway (depending on the line of sight). The GAIA A18 comes with an external WIFI/LoRA gateway.
The GAIA A18 also contains an internal GPS sensor to make it easier to locate your remote stations.
The GAIA A18 with both solar panel+battery and LoRa features connectivity costs .
It is also possible to get the A18 with only one feature (either Solar or LoRa) for :

For official stations, there are two more requirements, with the intent is to locate the station on sites representative of the ambient air quality levels (reference).
There are so many air quality related products on the market; Some are good, other are bad. For consumers like us, it can sometime be difficult to find out which product is good and worth buying and which one is bad and should not be bought. For this reason, we have created this 'Air Quality Products' page on which you will find a selection of products that we have carefully studied and evaluated.
| 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 |
