CESS: Closed environment safety system

Abstract

The worldwide spread of the COVID-19 disease has required the adoption of restrictions to protect public health. These rules have heavily changed the access to working places, damaging in-person business, which is still the core of global and local economies. From large corporations to small companies the main challenge is to keep working places open and functional to maintain productivity and efficiency standard under the application of the anti-Covid-19 measures. This paper describes the design, prototyping work, simulations and test procedures of a low-cost system designed to monitor the fluxes of people and air quality of target areas (e.g., company's offices) to warn about the exposition to risky condition and to model crowd flows around a building to advise virtuous behaviour and preserving safe working conditions. To do that, the system merges the data produced from different suits of sensors to create safe working environments and keeping in person business running.
