From the harbor city of Hamburg we develop our product based on the needs of real customers. We are funded by the European Union. Recently we have been awarded in the category "World Citizenship" of the Microsoft Imagine Cup. Professional air quality monitoring for cities has been a complex and expensive undertaking. Up until now. We focus on your specific needs and our solution works cost-efficient. It is merely the size of a shoebox. This allows you to easily attach it to facades and install it in public space. Our solution allows you to achieve an arbitrarily high data resolution and creates a basis for completely new fields of applications. In the future you will not only be able to recognize problems like traffic jams to initiate appropriate countermeasures. You can also analyze the impact urban development activities have on the urban climate, identify best practices and optimize your city layout. The possibilities are almost endless.
