Desarrollo de un dispositivo IoT en cloud para la medición de la contaminación auditiva en ambientes cerrados

Abstract

This project refers to the design of a wireless device for measuring noise in an enclosed space which uses an KY038 sound sensor to collect data in analogue form. The measurement of noise is a very important environmental technique as there are places that have regulatory provisions on the dangers of a noisy environment, there are parameters for the measurement that must be taken into account for the calibration of the KY038 sensor. The sensor collects the signal and amplifies it for subsequent reading with the ESP8266 embedded card that communicates with the MQTT server wirelessly as it uses Wifi technology. In addition, using the Node-RED software, it is proposed to carry out the programming using nodes that will be implemented to generate alerts and communicate the elements that make up the wireless system.
