The GAIA Air Quality Monitoring Stations are specially optimized, highly accurate, and easy-to-use monitoring stations designed by the Earth Sensing labs. The stations are suitable for affordable an budget - as low as 100 USD per year for the most recommended A12 station.




GAIA A12 Monitoring Station

Air Quality Monitors

The Gaia Ax series is a semi-professional Air Quality monitoring product range suitable for outdoor as well as indoor and industrial Air Quality monitoring and produced and manufactured by the Earth Sensing Labs from the WAQI project.

Accurate and Reliable

All the semi-pro stations have been carefully designed for highly reliable and accurate monitoring, using 3 redundant sensors and high-quality components. All the stations are tested individually, and produced in small batches to ensure the best quality.

Designed for efficiency

The GAIA station provides data as accurate as of the traditional high-end professional air quality monitoring stations (e.g. using BAM or TOEM) but at only 1/20th of their price. Together with the GAIA big-data cloud system, hundreds of stations can be deployed, maintained, and analyzed in a single city in just a few clicks.

The GAIA is also specially designed for outdoor use with IP67 waterproof material and UV-proof ABS plastic.

Gaia A18: Solar Powered & LoRA radio

Overview


Gaia A18 product view

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.

Battery and Solar Powered

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.

Battery:
  • Model: 18650 LiPO Battery (standard battery)
  • Capacity: 3400 mAh 3.7V (12.5 Wh)
  • Lifetime: 10+ days without solar harvesting
  • Sensing Cycle: 30 seconds every 5 minutes (configurable).
  • Power Consumption: 130µA (sleep mode), ~100mA (sensing mode)
Solar Panel:
  • Max output: 6V 500mA (3W)
  • Dimensions: 220 * 130 * 7mm
  • Weight: 260g
Station:
  • power cable: 10m waterproof solar panel power cable
  • Dimensions: 115 * 90 * 55 mm (excluding antenna)
  • Weight: 450g (excluding battery)

Enhanced Connectivity using LoRa ("Long Range")

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 optional internal GPS sensor to make it easier to locate your remote stations.

Frequently Asked Questions:

  • Payment: It is done at shipping time, and can be done using any regular credit card.
  • Discount: 10% discount when ordering 5 pieces, 20% when order 10 pieces or more.

Installation & Mounting Instructions

Mounting:

Mounting with strips
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 strips: The GAIA station is delivered with 2 strips of 1 meter, which can be used to fix the station on a pole.

Distance:

  • The station comes with a 10 meters (33 feet) 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 is using a regular external WIFI antenna, which allows the station to be at least 20 meters away from the nearest hotspot. In case a longer distance is needed, an enhanced external antenna can be used (contact us in this case).

Location:

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

Average daily traffic
(vehicles per day)
Minimum
≤1,000 10
10,000 10

≥110,000 250

    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).

  • 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 nearby the station.

  • Distance from road traffic: The station should be located at least 10 meters away from the nearest road. See table on the right for full specifications.
