Join us on Open Data Day 2019! As per our tradition we are hosting a hackathon on the global Open Data Day.
It'll definitely cover air quality sensor hacking. But we haven't ruled out other topics for the day such as the visualization of the air quality data just yet. If you want to engage or inspire us, feel free.
We've reused last year's website, because the project remains the same http://hackfrankfurt.de/
