Diseño e implementación de una red inalámbrica de sensores inteligentes para el registro de la contaminación acústica en la ESPOCH basado en tarjetas de desarrollo.

Abstract

The design and implementation of a wireless network of intelligent sensors for recording noise contamination at the Polytechnic School of Chimborazo is a real-time system based on wireless sensor development boards. The devices have been rigorously studied according to the compatibility with sensors, wireless transceivers and signals generated by external circuits; costs, feasibility and ease of installation, as a result the Arduino development board was elected. The design and implementation was based on a network to record noise levels shown in areas with increased human activity, measured in decibels (dB) using a noise sensor ideal for work that identified levels of noise pollution which causes health disorders. The Faculty of Computer Science and Electronics was chosen to measure changes in noise area, placing three modules: monitoring, storage and warning. The time measured was continued for seven calendar days. The information was store on a micro SD memory card and through the USB port of the Arduino board, they are displayed numerically and graphically the current, maximum and minimum values in a virtual tool developed in the LabVIEW software. It works with a mobile application Data Dashboard, which maintains a wireless communication through Wi-Fi network. It was found that the electronic monitoring system for noise contamination has a maximum absolute error of ±1,2 dB and instability 2%, showing that there is a moderate range of operation and that the system is reliable. The results represent the wireless network implemented with the electronic system is functional with a range for the transmission of 98 meters. By design features it represents a monitoring tool and recommended gathering information for studies to reduce levels of noise contamination after foresee conditions in the population. It is recommended to the authorities of the Polytechnic School of Chimborazo which is implemented the system designed to alert the polytechnic staff on noise levels to which it is exposed in their daily activities.
