share: aqicn.org/gaia/

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 $100 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 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 semi-professional 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 semi-professional gaia is also specially designed for outdoor use with ip67 waterproof material and uv proof abs plastic.

overview

gaia a12 product view

the gaia a12 is sensor-packed station:

air quality particulate matter sensors: 3x
meteorologic sensors:
connectivity via wifi, with external antenna.

the station is using 3 redundant air quality sensors to ensure the best data quality: our system continuously correlates the data from all sensors to automatically detect and correct any abnormal data.

the gaia a12 station is also very compact, light, so easy to install:

power supply: only needs a 5v (usb compatible) supply
power cable: 10 meters waterproof power cable included.
dimensions: 130 * 80 * 70 mm
weight: 380g

pricing

the station is sold at a cost of per month, or if paid yearly.

when purchased monthly (respectively yearly), you only need to pay for the station every month (resp. year) as long as you want to use it. you can stop the payment at any time. furthermore, every 2 years, we send you a brand new station for free (excluding shipment cost). renewing the station is important to us to ensure the highest sensor quality of your station.
note that we ask for a deposit for rented station.

alternatively, it is also possible to purchase the station with a one-time payment. in this case, the cost is .

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 the 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
15,000	20
20,000	30
40,000	50
70,000	100
≥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 ().

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.

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

gaia a13: with more gas sensors

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

ozone (o₃)

carbone dioxyde (co₂)

formaldehyde (ch₂o)

total volatile organic compound (tvoc)

carbon monoxyde (co)

nitrogen dioxyde (no₂)

sulfur dioxide (so₂).

gaia a15: with lorawan 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 connectivity, this station will allow connecting to the global .

gaia a18: solar powered ("off-grid")

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.
