Diseño de un prototipo multimodal utilizando tecnologías inalámbricas y móviles para monitorear en tiempo real la contaminación auditiva en el centro histórico de la ciudad de Riobamba.

Abstract

The objective of this degree work was the design of a multimodal prototype using wireless and mobile technologies in order to monitor the auditory contamination in real time at the Historic Center of Riobamba. The bibliographical research carried out allowed to determine causes and effects produced by noise, being the permissible limit value 80dBm according to the Secondary Environmental Legislation (TULSMA). It was also inquired in the topologies and characteristics of equipment that accomplish with the system requirement. The design and implementation of the prototype was carried out using a star topology, the teams were chosen for their easy acquisition and low power consumption, these are: MAX4466 sensor, Arduino UNO and GSM SIM800C with a CLARO chip. For the virtual processing, we opted for the Thingspeak platform and the App Inventor environment. In addition to measuring noise, this system has a method of sending text messages, when this exceeds the permissible limit. For the tests, five sectors were chosen: Parque Sucre, Plaza Alfaro, La Merced, Parque Maldonado and Plaza Roja, likewise, four schedules of 60 minutes each were scheduled. Subsequently, a quantitative analysis of all the data obtained in each sector was carried out to validate the noise level results, in addition to verifying the efficiency of this prototype with reference to a sound level meter that was installed in a mobile phone. The results were favorable in relation to the functioning of the prototype because the values obtained were within of measured range with the mobile application. The sector which presented the greatest noise during one day and exceeded more times the limit level was the Parque Sucre. It is recommended to carry out a deeper study about devices in order to optimize the program of operation and ensure better response time and system performance.
