Abstract

In times of 5.0 technologies, concern with the environment and the development of sustainable devices affect all the agro-industrial sectors of the world. A lot has been researched in terms of the application of alternative energies and effective treatments for residues and excrement dumped by industries and large rural producers directly into the most diverse environmental niches. Biofuels emerge as a promising and less aggressive alternative to the world, allowing the burning of less powerful fuel in exchange for the emission of pollutant gases on a smaller scale. Currently, one of the main biofuels that have been studied and applied is biomethane, produced mainly by the action of digesters, in which through the anaerobic digestion of organic materials, together with a dosage of water, result in biofuel. However, most of the biodigesters available on the market require high implementation costs, especially for farmers linked to family farming. In this context, the main objective of this project is the development, in an institutional environment, of a sustainable onboard system, of low cost and energy expenditure, for the measurement of physical-chemical parameters inside a biodigester in order to measure the production of gases. The methodology is divided into 3 main steps, being the hardware development followed by the firmware and finally the field testing. As a result, it is intended that the embedded system is able to monitor - in real time - the proportions of gases and pressure inside a biodigester and send the data to the user, allowing the user to have knowledge of what is being generated inside his equipment. In addition, it is proposed to analyze two types of control for the system and compare them in terms of cost benefits and energy efficiency.
