The growing production and disposal of organic waste generates an environmental, economic and social concern, which pressures, the responsible, the resolution of the problems caused by this factor. Thus, the creation of Law No. 12,305 / 10 and Decree No. 7,404, of December 23, 2010, the National Solid Waste Policy (PNRS), helps in the proper disposal of waste and sustainable consumption, providing the possibility of realization. waste treatment and reuse. Organic composting of waste is a form of treatment that requires the completion of a process that involves factors to be analyzed, technologies and equipment to be defined according to the capacity of each agent. Thus, the objective of this work is to monitor, in an automated way, a composting process, using sensors capable of real time data acquisition and control of the presented parameters. The materials for assembling the composting system were established according to the availability of waste and the determination of the process based on the capacity of the facilities and the tools required for analysis and process monitoring. The results showed that there is a need to monitor the parameters of composting processes, thus contributing to the acquisition of reliable data and providing real-time decision making; the windrow has points with different parameters at the same composting time; the center of the windrow does not behave the same as the outermost points; Automated monitoring can be applied to any composting process as long as there is daily monitoring of the entire system. Based on the results obtained, it can be concluded that the composting system is a sustainable alternative to waste disposal problems and the process automation allows the analysis of the parameters that influence the optimized compost treatment.
