ArdOmino is a low-cost solution, based on Arduino technology, to capture data ﬂows through specific sensors and raise local environmental awareness. ArdOmino is a “talking sensor” thought to register, interpret and share data in the form of conversation on social media platforms. The ArdOmino framework is conceived to turn numerical data into human relevant and human readable information and use the engagement of local communities to validate the data itself. Geo-tweets will be interpreting environmental information (as weather) by communicating perceived state by people, resulting not only in a simple real-time social data validation but giving a collective awareness face to the environment. Data are already shared as numerical information, but in this case the interpretation of the data itself is left to people competences, in lack of right competences this can interphere with the process of making awareness decisions. The idea of ArdOmino is to provide the system with an "interpretation model" of data useful on to create more communicative/informative messages to be shared on social media. This more informative communication style would integrate the data flow deliverd to people, increasing the culture of data and empowering citizens to take more informed decisions.
