On April 16 and 17, 2020, the third edition of the Sensor data challenge was held by The Hague University of Applied Sciences, Statistics Netherlands, Utrecht University and the National Institute for Public Health and the Environment. The Sensor data challenge provides hardware (various sensors, raspberryPI) and software to teams with a mix of expertise in electronics, mechatronics, data science, user experience and industrial design. Teams need to design a tool and demonstrate its feasibility and relevance for one of the presented challenges.

The third challenge had sensor measurements for living and working as the central theme. Winning solutions of the two previous editions have been the starting point for large-scale ongoing research projects. We like to present a brief summary of the solutions presented by the participating teams at the third challenge and offer the winning team the opportunity to share and discuss their ideas at the BigSurv20 with a larger audience.
