Motion detection system with ultrasound sensor and Arduino to control the capacity of tourists

Abstract

Introduction: As a result of the pandemic caused by the Sars-Cov-2 virus, countries have imposed measures so that estab-lishments can gradually normalize their activities in a transi-tion stage that points to economic reactivation in the tourism sector. For the reopening of the scenarios arranged in cultural tourism, it is necessary to strictly comply with social distanc-ing and avoid crowds, which is why it is essential to limit the capacity or the capacity of visitors.

Objective: To present the design of a data acquisition pro-totype using an HC-SR04 ultrasonic sensor programmed with Arduino, whose implementation allows to control the maximum capacity of tourists in closed environments such as museums, libraries, theme parks, buildings, art galleries and archaeologi-cal sites.

Methodology: The implementation of a system based on IoT and data analytics in a tourism context was proposed. Pro-gramming with Arduino code allowed the capture and visual-ization of data for 48 hours.

Results: Through the analysis of the captured information, it was possible to alert about the maximum capacity established for the parameterized capacity of visitors, identifying through the notifications the risk levels.Conclusions— The developed system allows alerting about the maximum capacity in closed spaces, generating control and reducing the probability of contagion in these spaces.
