Parts

Things you need to supply

CityOS does not sell these devices, but you have a few options on how you can get one or few:

  1. You can build it yourself using these tutorials,
  2. You can come to our free workshops organized each time 5 or more people contact us with ready parts for their stations,
  3. Pay one of the many students we trained to build you one.

Parts for the full version cost about 50 EUR depending on where you order them, and we recommend paying students about 20 EUR per station if you want to go that way.

That is "Data Giver" version, but you can also build "Data Taker" version with no sensors. It is just a lamp that gets data from the server from your neighbor's station. It will still light up like a full setup version to notify you of pollution but you will not be able to measure your indoor data or to contribute data for the movement.

This section lists the parts you will need to successfully build your own CityOS Air device (Boxy).
