Gaia Air Quality Monitors - Product Series

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 $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.

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.

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.

Product Series

The product series currently consists in 5 different monitors. The first two ones, A11 and A12 are fully functional, fully tested and production ready. They are specially designed for outdoor Particulate Matter sensing (aka PM2.5/PM10), which is, most of the time, the 'worst' pollutant among regular atmospheric pollutants.

The last three ones, A13, and A18 and A19 are still in R&D development phase. They bring additional gas sensing such as Ozone. They also have the ability to operate off-grid, i.e. without need for a power-supply, by running on photo voltaic solar panel.

All products are 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 during the past 2 years and are now production ready.


A11 Dimensions

Gaia A11: Personal Sensing Station

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 (PM2.5, PM10) as well as one for Relative Humidity and Temperature.
  • PM Sensors: 1x PMS 5003
  • Met Sensors: DS18B20
  • Power Supply: 5V (USB compatible)
  • Connectivity: WIFI (with embedded antenna)
  • Dimensions: 65 * 95 * 55 mm

Gaia A12: Professional Sensing Station

The Gaia A12 comes with 2 redundant PM sensors (so 3 in total). This setup is mandatory for “official” AQI readings (eg. readings broadcasted to a wide audience), as a way to ensure the data reliability of the PM sensors.

Gaia A12 product view
The meteorological sensor is upgraded to high precision sensor for Relative Humidity, Temperature and Pressure sensing.
  • PM Sensors: 3x PMS 5003
  • Met Sensors: BME 280
  • Power Supply: 5V (USB compatible)
  • Connectivity: WIFI (with external antenna)
  • Dimensions: 130 * 80 * 70 mm

Gaia A12 GSM: Professional A12 with GSM connectivity

The Gaia 12 GSM is a variant of the standard Gaia 12 GSM. It comes with an additional GMS (SMS/GPRS/4G) module - which can be convenient for remote locations without WIFI access but with power supply available.

We also provide the GSM/SMS back-end support for most of the countries in the world, so you do not need to worry about managing the data. If you want to use your own SIM card, the average data consumption is about 4MB (mega bytes) per month - make it suitable for the traditional M2M SIM cards.
For the cost, please refer to the configuration and pricing summary table below.

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).

Devices Under Development

The following devices are under development and expected to be ready in Q1 2017.

Gaia A13: Gas Sensing

The Gaia A13 is based on a standard A12 professional configuation, but with an additional Gas sensor. It can support different gas sensing:
  • Formaldehyde (CH2O)
  • Total volatile organic compound (TVOC)
  • Carbon Dioxyde (CO2)
  • Carbon Monoxyde (CO)
  • Nitrogen Dioxyde (NO2)
  • Sulfur Dioxide (SO2).
  • Ozone (O3).
Please note that one Gaia A13 station can only accommodate one Gas sensor, so you can only choose one from the above list. If you need a solution with more than one gas sensing in one station, please contact us first.

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 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).
