SpaceEcho operates an outdoor air quality station in Helwan for the National Research Institute of Astronomy and Geophysics (NRIAG). It sits near an industrial area and reports particulate matter, gases and weather data in real time.
SpaceEcho operates an outdoor air quality monitoring station in Helwan for the National Research Institute of Astronomy and Geophysics (NRIAG). The station sits near an industrial area and supports NRIAG's environmental and scientific research.
The challenge
Air near an industrial area changes through the day with emissions, wind and weather. To study it, researchers need particle, gas and weather readings from the same place, at the same time.
Dust is the second problem. It settles in the air path and on the sensors, and a clogged sampler gives wrong readings.
What we installed
An ECHO-AQ air quality station: the AQS air quality unit and a weather sensor on one mast.
Particulate matter and gases — particulate matter (PM1, PM2.5 and PM10), hydrogen sulfide (H₂S), ozone (O₃), nitrogen dioxide (NO₂), carbon monoxide (CO) and carbon dioxide (CO₂).
Weather — air temperature, humidity, pressure, wind speed and wind direction.
Two-fan air intake — two fans draw air through the unit, each with its own speed, so the sample that reaches the sensors is controlled.
Self-cleaning — the fans run at higher power to blow dust and debris out of the air path.
Remote management — fan settings are read and changed remotely.
NRIAG receives real-time particulate matter, gas and weather readings from one station near an industrial area. Researchers and decision-makers use the data to evaluate pollution levels and follow how they change over time.
