GAIA A12 product view

Dimensions: 130 * 80 * 70 mm
(excluding antenna)
Weight: 380g

The GAIA A12 is a sensor-packed station:

• Air Quality Particulate Matter Sensors: 3x PMS 5003
• Meteorological Sensors: ASAIR AHT-20
• RGB led for real-time visual Air Pollution indication.
• Connectivity via WIFI, with an external antenna.
• Optional SD-Card storage for off-network operation.

The GAIA A12 uses 3 redundant Air Quality sensors to ensure the best data quality: Its system continuously correlates the data from all sensors to automatically detect and correct any abnormal data.

The GAIA A12 station comes with the following accessories:

• Power Cable: 10-meter (2x5m) waterproof cables.
• Power Supply: USB 5V/1A power adapter.
• Fixation straps and screws.

The GAIA A12 costs 200

Alternatively, the station can also be acquired for 100 if paid yearly, or 10 if paid monthly: We then send you a brand new station every 2 years for free (excluding shipment costs). Renewing the station is important to us to ensure the highest sensor quality of your station. Note that we ask for a 50 deposit for the rented station.

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 (when using LoRa). The solar panel battery can recharge the battery within a few hours under direct sun conditions. Using both the solar panel and the battery, the station can operate forever off-grid, provided there are a few sunny days every week.

Battery & Power Consumption:

• Battery Model: 18650 LiPO battery (standard battery)
• Capacity: 3400 mAh 3.7V (12.5 Wh)
• Lifetime: 7+ days without solar harvesting (using LoRa)
• Sensing Cycle: 30 seconds every 5 minutes (configurable)
• Power Consumption: 130µA in sleep mode, ~100mA in sensing mode

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 kilometers 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 optional 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 350.
It is also possible to get the A18 with only one feature (either Solar or LoRa) for 280.
Support for the GPS cost an additional 50.

Mounting with straps

Mounting with screws

There are 2 options for mounting the monitoring box:

• Using screws: The GAIA enclosure is made of a standard outdoor ABS box, which comes with 4 holes dedicated to screwing the box.
• Using standard plastic straps: The GAIA station is delivered with 2 straps of 1 meter, which can be used to fix the station on a pole.

• The station comes with a 10-meter (33-foot) power cable (5V with DC3.5 connector), so the station should be located no more than 10 meters away from the nearest power source. If needed, we can provide a longer power cable (contact us in this case).
• The monitoring station uses a regular external WIFI antenna, which allows the station to be at most 20 meters away from the nearest WiFi access point. In case a longer distance is needed, an enhanced external antenna can be used (contact us in this case).

Overall, the most important is to place the station somewhere protected from direct winds, rain, and dust sources.

For official stations, there are two more requirements, with the intent to locate the station on sites representative of the ambient air quality levels:

• Height: The station should be mounted at a height above a minimum of 1.5 meters. The objective is to prevent dust resuspension, which can happen if someone is walking near the station.
• Distance from road traffic: The station should be located at least 10 meters away from the nearest road. See the table on the right for full specifications.
