I have chosen "Guerrilla Gardening" as the theme for my website because I can make good and useful use of the environmental sensors offered. Guerrilla Gardening means planting vegetable gardens in cities, on balconies and terraces. Sometimes also on illegal areas. On my website I will provide useful links and own contributions besides the sensor values for fine dust, temperature and air pressure. Please have a look to my video "making of guerilla garden" about all the details:
