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 $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.

Production Ready Devices

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

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 a 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
The station is sold as "hardware-as-a-service", meaning that you pay for the station every month as long as you want to use it. You can stop the payment at any time. Then, every 2 years, you receive a brand new station (renewing the station is important to ensure the highest quality of the sensors).

The station cost is per month.

Gaia A13: Additional gas sensors.

The Gaia A13 is based on a standard A12 professional configuration, with the possibility to add one (and only one) additional Gas sensor. Currently, two different kinds 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 that 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 station is sold as "hardware-as-a-service", meaning that you pay for the station every month as long as you want to use it. You can stop the payment at any time. Then, every 2 years, you receive a brand new station (renewing the station is important to ensure the highest quality of the sensors).

The station cost is per month.

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 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.

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 of the ambient air quality levels (reference).

Average daily traffic

≥110,000 250
  • 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.

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).

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 connectivity, this station will allow connecting 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 as 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).

    Về các thang đo chất lượng không khí

    - Giá trị chỉ số chất lượng không khí (AQI)Mức độ ảnh hưởng sức khỏe
    0 - 50 Tốt Chất lượng không khí được xem là đạt tiêu chuẩn, và ô nhiễm không khí coi như không hoặc gây rất ít nguy hiểm
    51 -100 Trung bình Chất lượng không khí ở mức chấp nhận được; tuy nhiên, một số chất gây ô nhiễm có thể ảnh hưởng tới sức khỏe của một số ít những người nhạy cảm với không khí bị ô nhiễm.
    101-150 Không tốt cho người nhạy cảm Nhóm người nhạy cảm có thể chịu ảnh hưởng sức khỏe. Số đông không có nguy cơ bị tác động.
    151-200 Có hại cho sức khỏe Mỗi người đều có thể sẽ chịu tác động đến sức khỏe; nhóm người nhạy cảm có thể bị ảnh hưởng nghiêm trọng hơn.
    201-300 Rất có hại cho sức khỏe Cảnh báo nguy hại sức khỏe nghiêm trọng. Đa số mọi người đều bị ảnh hưởng.
