The pulse of Berlin

An agile footing can go a long way to succeeding

By Benjamin Seibel and Yi Jun Huang

The windows in this pre-war building on Skalitzer Straße vibrate to the beat of the U1. The morning traffic flows to the rhythm of the traffic lights. Rubbish bins are filled and emptied, again and again. And the temperature and time of day determines how and where we prefer to spend our time. Data flows through our city like a constant pulse. With the new website Stadtpuls, we have created an open platform that supports the collection and visualisation of sensor data as well as the provision of this data for further data analysis. How noisy is it in my street? What is the CO2 level in my classroom? Is it warmer in Wedding than in Friedrichshain? Just how polluted is the air at doorstep? Stadtpuls wants to help explain your environment. 

You feel your pulse rising? Let us know!

With the launch of the beta version, we want to invite you to become part of the community and connect your own sensor data to the platform. You can create your own account on within just a few minutes and already start connecting your sensor projects via TTN or HTTP. Stadtpuls publishes your data in the form of graphical visualisations and provides both links where measurement data can be downloaded as well as an API endpoint for each connected sensor. This increases the visibility of your project and makes it as easy as possible for others to work with your data. Citizen science meets data-driven journalism!

Tell your story

Our colleagues from ODIS will also show you how data can be transformed into rich stories. They captured the soundscape of Kreuzberg’s Wrangelkiez and turned it into a storytelling project:

And that’s just the beginning! Together with you, we are developing Stadtpuls into an IoT hub for Berlin’s sensor data. In the new year, you can look forward to workshops and hackathons through which we hope to make the pulse of our capital city visible.
