The measurement points, disguised as birdhouses, change colour to reflect changes in the quality of the air. The devices then send this data to a public website. Collecting data, making it publicly accessible, and providing information about potential hazards is helping to create a healthier future.

The birdhouses accurately measure nitrogen dioxide (NO2) concentrations, humidity levels, and air temperature. NO2 concentrations are a reliable indicator of the amount of soot particles present in the air we breathe. It’s important to monitor soot particles instead of other fine particulate matter such as sand or salt, as these are harmless. The information is collected, interpreted, and then published on a website that includes all available measurement points and data. This allows the data to be accurately compared and interpreted. The website also explains air pollution in more detail.

Bureau Marineterrein Amsterdam installed its first measurement point near the old gate at Kattenburgerweg 5. Plans are currently being developed to install more measurement points in the future and to publish the data on the website of Marineterrein Amsterdam. Founder of Treewifi, Joris Lam, is a member of Makerversity at the Marineterrein Amsterdam.
