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.

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 (PM2.5, 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).

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).

    本網站採用的污染指數和顏色與EPA是完全相同的。 EPA的指數可以從 AirNow上查到

    空气质量指数 空气质量指数级别(状况)及表示颜色 对健康影响情况 建议采取的措施
    0 - 50 一级(优) 空气质量令人满意,基本无空气污染 各类人群可正常活动
    51 -100 二级(良) 空气质量可接受,但某些污染物可能对极少数异常敏感人群健康有较弱影响 极少数异常敏感人群应减少户外活动
    101-150 三级(轻度污染) 易感人群症状有轻度加剧,健康人群出现刺激症状 儿童、老年人及心脏病、呼吸系统疾病患者应减少长时间、高强度的户外锻炼
    151-200 四级(中度污染) 进一步加剧易感人群症状,可能对健康人群心脏、呼吸系统有影响 儿童、老年人及心脏病、呼吸系统疾病患者避免长时间、高强度的户外锻炼,一般人群适量减少户外运动
    201-300 五级(重度污染) 心脏病和肺病患者症状显著加剧,运动耐受力降低,健康人群普遍出现症状 儿童、老年人及心脏病、肺病患者应停留在室内,停止户外运动,一般人群减少户外运动
    300+ 六级(严重污染) 健康人群运动耐受力降低,有明显强烈症状,提前出现某些疾病 儿童、老年人和病人应停留在室内,避免体力消耗,一般人群避免户外活动
