Share: aqicn.org/gaia/a08/

Overview

Gaia A08

Dimensions: 50 * 47 * 30 mm
Weight: 180g

The GAIA A08 is a compact and open-source air quality monitoring station that is ideal for indoor or outdoor use.

  • Air Quality Particulate Matter Sensors: 1x PMS 5003 (possible to connect up to two PMS sensors)
  • Meteorological Sensors: ASAIR AHT-20
  • RGB led for real-time visual Air Pollution indication.
  • Connectivity via WIFI, with an internal flex antenna.

The GAIA A08 is suitable for indoor and outdoor air quality monitoring. The RGB LED provides immediate feedback on indoor air quality, and its mechanical structure ensures rain-proof operation when used outdoors.

The GAIA A08 station is compact, easy to install and comes with accessories.

  • Power Supply: USB 5V/1A power adapter.
  • Power Cable: 1 meter USB cable.
  • Fixation straps and screws.

The GAIA A08 is preloaded with the plug'n'play aqicn.org software: So you can just plug the power and the device will automatically report the data on to our maps. You will get access to our internal dashboard where you can check the real-time and historical data, as well as update the device coordinates on the map.

Open Source

For those who want to develop their own custom software, the GAIA 08 comes with open-source Arduino-compatible software, available at https://github.com/aqicn/gaia-a08-arduino.

The GAIA A08 allows you to flash your own firmware just by using the USB cable. And you can always reflash the original aqicn.org software (firmware.aqicn.org/gaia/updater)

The CPU is an Espressif ESP32-C3 with 4MB of Flash. The hardware mother board comes with an extension connection which provides means to connect external sensors (one free GPIO, two TX/RX GPIOSs, two 3.3V and 5V power and ground are available).

Flashing and console monitoring can be done via the USB port, meaning you do not need any additional serial TTL adapter.

The ready-to-use arduino software allows uploading the GAIA 08 real-time data onto the aqicn.org and waqi.info maps.

About the Air Quality Levels

AQI Air Pollution Level Health Implications Cautionary Statement (for PM2.5)
0 - 50 Good Air quality is considered satisfactory, and air pollution poses little or no risk None
51 -100 Moderate Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
101-150 Unhealthy for Sensitive Groups Members of sensitive groups may experience health effects. The general public is not likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
151-200 Unhealthy Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
201-300 Very Unhealthy Health warnings of emergency conditions. The entire population is more likely to be affected. Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
300+ Hazardous Health alert: everyone may experience more serious health effects Everyone should avoid all outdoor exertion
