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 budget - as low as $200 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 redundant sensors and high quality components. All the stations are tested individually, and produced is small batches to ensure the best quality.

Designed for efficiency

The semi-professional GAIA station provide data as accurate as 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 few clicks.

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

Production Ready Devices

The following devices have been developed and tested since 2017 and are now production ready.

Gaia A11: Personal Sensing Station

A11 Dimensions

The Gaia A11 is the most simple version of the series, but also the most affordable. It comes with 2 integrated sensors, one for Particulate Matter (PM_2.5, PM₁₀) as well as one for Relative Humidity and Temperature.

Particulate Matter Sensors: 1x PMS 5003
Dimensions: 65 * 95 * 55 mm

Station cost is $100.

Gaia A12: Professional Sensing Station

Gaia A12 product view

The Gaia A12 comes with 2 redundant PM sensors (so 3 in total). This setup is mandatory for “official” AQI readings (eg. data broadcasted to a wide audience), as a way to ensure the data reliability of the PM sensors. The meteorological sensor is an high precision sensor for Relative Humidity, Temperature and Pressure sensing.

Particulate Matter Sensors: 3x PMS 5003
Meteorologic Sensors: BME 280
Power Supply: 5V (USB compatible)
Connectivity: WIFI (with external antenna)
Dimensions: 130 * 80 * 70 mm
Weight: 380g

Station cost is $200.

Gaia A13: Additional gas sensors.

The Gaia A13 is based on a standard A12 professional configuration, with the possiblity to add one (and only one) additional Gas sensor. Currently, two different kind of gas sensors are supported.

Ozone - O₃

Detection Range: 0~10 ppm
Resolution: 10 ppb resolution
Sensor ZE25-O3.

The Ozone (more specifically the ground level Ozone) is a gas which is formed when heat + sunshine + traffic emissions are present together. It is usually active during mainly Summer, especially in the afternoon. During winter, or night, it is not a relevant pollutant.

Carbon Dioxide - CO₂

Detection Range: 0~2000 ppm
Resolution: 50 ppm resolution
Sensor MH-Z19B

Carbon Dioxide, more know for its global warming effect, is more relevant for indoor sensing. When used outdoor, concentration levels are low with small variation, and without direct health impact (but strong indirect humanity impact). We recommend this sensor only for academics working on CO2.

The GAIA A13 Station cost is $250.

Gaia A12 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 standard outdoor ABS box, which comes with 4 holes dedicated for screwing the box.
Using standard plastic strips: The GAIA station is delivered with 2 strips of 1 meter, which can be used to fixed the station on a pole.

Location:

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 is to locate the station on sites representative to the ambient air quality levels (reference).

Average daily traffic (vehicles per day)	Minimum
≤1,000	10
10,000	10
15,000	20
20,000	30
40,000	50
70,000	100
≥110,000	250

Height: The station should be mounted at a height above a minimum of 1.5 meters. The objective is to prevent from 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 specification.

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 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 longer distance is needed, enhanced external antenna can be used (contact us in this case).

Ordering and Inquiry

If you are interested in getting a GAIA station, send us a message and we will allocate one station in the current batch. If you to place an order, please indicate your address and phone number for the delivery. Payment is done at shipping time, and can be done using any regular credit card or paypal.

Devices Under Development

The following devices are under research and development, and not yet available for production:

Gaia A13++: More gases

Also, we are currently evaluating sensors able to monitor the following gases.

Formaldehyde (CH₂O)

Total volatile organic compound (TVOC)

Carbon Monoxyde (CO)

Nitrogen Dioxyde (NO₂)

Sulfur Dioxide (SO₂).

Gaia A12 LoRa: A12 with LoRa connectivity.

We initially worked on a GSM version of the Gaia A12, but as the GSM connectivity is fading away, it is not a future proof solution. So, for those who have no WIFI conenctivity, this station will allow to connect to the global things network.

Gaia A18: Off-grid Sensing

The Gaia A18 is the same as the Gaia A12, but can be operated without D/C power supply, via the 3 cells battery and the included solar charger.
Under normal solar conditions, the box can be operated for at least 3 months without charging. Without, it can operate for a minimum of one month (depending on the sampling frequency).
The Gaia A18++ variant is packed with a total of 9 cells, making it able to last 1 year under normal solar conditions.

Gaia A19: Professional Off-grid

The Gaia A19 is the most advanced of the current Ax series. It includes both GSM/3G/LORA Network connectivity (in case WIFI is not available), as well a GPS sensor for positioning the box.
The embedded battery is extended to a 9 cell battery, allowing the box to run for a minimum of one year without D/C charging (under normal solar conditions).

All Products

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.
