Diseño e implementación de un prototipo de medición de emisión de gases contaminantes en el laboratorio de automotriz de la Universidad Politécnica Salesiana Sede Guayaquil

Abstract

This project arises as a result of the study of different factors that affect the atmosphere, the causes of harmful gases and pollutants to which we are exposed and the students of the UPS automotive laboratory could be exposed. This is the reason why the idea of creating a prototype for measuring polluting gases has come and that allows a study to be carried out, both in the physical space where it will be placed and in the future in daily life, since the passage of vehicles to daily in the avenues of our city is what causes the expulsion of gases through the exhaust pipe and therefore pollution around us.

The prototype consists of the use of four sensors: the MQ-7 for the measurement of carbon monoxide, MG-811 for the measurement of carbon dioxide, MQ-4 measurement of methane gas and O2 for oxygen. The data measured by the sensors will be sent to the pins of an Arduino nano. This will read the data read by the 4 sensors and send the data to the Raspberry PI3 to USB. The Raspberry PI 3 reads the data sent by the Arduino in the Python programming language; it stores it in a MySQL database to record said data.
