The CITI-SENSE Citizens’ Observatories Web Portal provides an access point to all our apps, widgets, web pages and sensor based tools and questionnaires. You can get information about how to acquire, install and use them. You can also access the data already collected. For the technically minded, you can get information about the sensing devices, and about how to use our data for your own applications. And of course, you can also learn about the project that brought this to you, CITI-SENSE, and links to our social media platforms. Visit co.citi-sense.eu today and provide us with your feedback!
