Hoi Arjen. This is documented at [sensors-software/airrohr-firmware at master · opendata-stuttgart/sensors-software · GitHub](https://github.com/opendata-stuttgart/sensors-software/tree/master/airrohr-firmware) at the end of the Readme.md.

X-Pin should be 1, same as SDS011. Also have a look at [Failing to post data to Madavi - #4 by Bert1](https://forum.sensor.community/t/failing-to-post-data-to-madavi/1759/4) which might be a similar issue.
