Join the project

AirQuality.city grows more slowly than a commercial product, but that also means a practical contribution can make a visible difference. A new monitoring location, a spare Raspberry Pi that can still do useful work, help with code or a well-researched article can be more valuable than an ambitious plan that never reaches production.

If the project interests you, there are several useful ways to get involved.

Host a SensorBox

The most valuable locations are places where local measurements are missing or where denser coverage would add meaningful information. A SensorBox needs an outdoor position protected from direct rain and strong sunlight, continuous power and a stable internet connection. Air must be able to circulate freely, and the unit should not sit directly beside a chimney, ventilation outlet or another source that would make the reading unrepresentative of the surrounding area.

Before installing a station, we can assess whether the location is useful and agree on a sensible mounting position.

Contribute hardware

The project uses Raspberry Pi computers or comparable devices, particulate-matter sensors, weather sensors, enclosures, networking hardware and small electronic components. Equipment does not have to be new; reliability and suitability for continuous operation matter more.

If you have unused hardware, contact us before sending or buying anything. It is easier to check compatibility first than to find a purpose for the device afterwards.

Help build the portal

AirQuality.city is more than a sensor network. Behind the map and charts are data collection services, backend systems, a web application, processing logic, station monitoring and a collection of small tools that keep the system running.

Contributions can be technical, visual or infrastructure-related. People interested in data, visualisation, web development, Raspberry Pi systems and small automation tools are particularly useful. The SensorBox station code is also available on GitHub, so part of the project can be explored before getting in touch.

Write, review or suggest topics

The portal is also developing a stronger editorial section. If your work or expertise touches air quality through environmental science, meteorology, medicine, chemistry, transport or another relevant field, a careful review of an article can be as valuable as hardware.

Topic suggestions are welcome as well, especially when they start from a concrete local problem, an interesting dataset or a question that people repeatedly ask.

Get in touch with something concrete

There is no application form. A short message explaining what you can offer, where you are based and what you would like to work on is enough. If you are offering a monitoring location, a few photos and an approximate location are useful.

Write to contact@airquality.city. If the idea fits the project, we will work out the simplest way to turn it into something useful.
