Desarrollo de un sistema IOT para el monitoreo del nivel de ruido existente en un entorno suburbano de la ciudad de Riobamba.

Abstract

Noise pollution in Ecuador is an underestimated event that affects thousands of people, causing various health issues. Excessive noise is a problem arising from factors such as vehicular traffic, industrial activities, businesses, and construction works, among others, frequently surpassing the maximum levels established by current regulations. The World Health Organization considers noise levels exceeding 65 decibels (dB) detrimental to health. Therefore, the objective of this project focuses on developing an IoT system to monitor the noise level in the suburban environment of Riobamba, aiming to continuously analyze the area using advanced technologies and software tools to identify and act upon critical points where noise levels are highly harmful to residents. Node-Red played a fundamental role in managing the system, allowing real-time visualization and manipulation of data captured by sensors in various locations. The process involved three stages: data collection through sensors, designing a graphical interface using Node-Red to visualize the data, and validating these data by comparing them with other measurement tools. The results of this project conclude by validating the noise samples obtained, enabling the proposed IoT system to replace the use of professional sound level meters and simultaneously capture noise generated in a much broader area to take corrective actions and prevent high noise levels in densely populated areas, where constant exposure can severely affect health. This project revealed the absence of a noise control system in Riobamba and the lack of information on health risks caused by continuous noise exposure.
