Sensor Network Prototypes for Environmental Noise Monitoring Based on Free Software

Abstract:

At present we are exposed to various polluting phenomena, one of these is environmental noise. In general, the environmental noise is not being monitored or controlled by the authorities in Ecuador, this led to this contribution to the ICF (Internal Competitive Fund) project “Noise pollution measurement systems in learning environments" in University of Guayaquil. In this article, a review is made of the studies carried out in countries such as Mexico, Peru and Chile on noise pollution that affects people’s health. Several works related to ours that have been developed under various platforms are also disclosed. The methodologies used have been descriptive research and PPDIOO (PPDIOO stands for Prepare, Plan, Design, Implement, Operate, and Optimize) for the implementation of two prototypes of environmental noise sensors. This hardware and free software monitor in real time the noise levels measured in decibels to which students and teachers of the Faculty of Mathematical and Physical Sciences of the University of Guayaquil are exposed. It will demonstrate the noise levels to which the academic community is exposed and make the authorities aware of it. Laws can then be generated to reduce this pollution that affects the health and well-being of the population. In the results, values greater than 50 dB were obtained during the working day.
