Design and Implementation of a Distributed IoT System for Monitoring of Gases Emitted by Vehicles That Use Biofuels

The global consumption of fossil fuels such as diesel and gasoline represent a considerable per-centage of global emissions, it is important to know for sure the percentage and type of gas emitted, there are many alternative energies that mitigate the production of emissions in different sectors such as the transport sector and the energy sector. The percentage use of hydrogen mixed with gasoline in internal combustion engines is a viable alternative because it helps the com-bustion process, but it is necessary to know the behavior of the engine and determine the carbon footprint, to quantify the benefit of these actions it is necessary to design and implement a network of low-cost sensors that monitor the emissions produced during the combustion processes and provide reliable data that can be used to make a statistical comparison between vehicles. This research proposes two software systems of an architecture (client-server) working in a synchro-nized manner in order to collect and store information in a database. The first software works as the client and runs on an IoT development board called ESP32 in conjunction with esp32 ttgo and communication between both devices is done through the esp now protocol, this software estab-lishes the connection with the physical sensors to detect and collect gas information, the data is sent wirelessly to the web server, the second software works as a server in addition to providing a graphical interface for user control and data visualization from a ground station. The tests were carried out using 100% Mexican gasoline (G100) and a mixture of hydrogen fuel with gasoline (GH) for the hydrogen cell a concentration of 0.0211 ml / gal of electrolytes (80 ml) was used, the same route and vehicle were used at an average acceleration of 40 and 60 km / h, the data obtained are taken every 30 seconds, the process was repeated 3 times and an average emission reduction of 5% and 10% of CO and CO2 respectively was obtained with GH fuel.
