Climate Change and a greater awareness of health and quality of life issues in urbanized environments are leading more and more to think about the concept of Smart City and sustainable development. Sense Square boasts years of experience, research and development in the field of IoT Technologies for High Resolution Environmental Monitoring, with 5 registered patents and more than 40 scientific publications that talk about our work. We generate value from the collection of territorial data through a platform business model and a synergy between infrastructure partners, administrations and companies. We create hybrid infrastructures for monitoring with high spatial and temporal resolution, enhancing existing infrastructures and generating smart services for citizens, companies and public administrations. The data collected is geo-localized and systemized in a multi-source logic, the software and algorithms developed by Sense Square are able to manage data from proprietary stations, satellites, public and European bodies. The final data is then interpreted, processed and represented in a transversal interpretation and directly interconnected with segments and market needs.
