The current pandemic caused by the SARS-CoV-2 virus has affected all sectors of activity through quarantine measures imposed to stop the spread of the disease. In the absence of safe treatment, social distancing and wearing a face mask are the only weapons to combat this pandemic. Unfortunately, social distance has led to the migration of education to a distance format reducing the interaction between teachers and students. Even if, through the vaccination process, the spread of COVID-19 disease will be slowed down, the physical return to schools and universities will be done under the sign of social distancing and health precautions. This article proposes a simple and low-cost solution for monitoring the density of people in a room by monitoring WiFi traffic. Because the solution can be implemented on a large scale, it is suitable for implementation as a centralized monitoring and warning solution at school or university campus level.
