The present work aimed to employ the replacement of traditional fiber by fiber from native palm and horse feces as a biocatalyst in the composting process. And to evaluate the process, a prototype microcontroller board was developed, like Arduino Uno R3, which monitored the parameters of temperature and humidity. The experimental design was: T1 - Control: 50% fibrous material (grass and leaf cuttings), 25% food remains and 25% horse feces; T2 – 50% fiber (Babaçu Fiber Shredded) 25% food scraps and 25% horse feces; T3 – 50% fiber (Babassu bark), 25% food waste and 25% horse feces; T4 – 50% fiber (broken babassu), 25% food waste and 25% horse feces. After 30 days of experiment, the samples were sieved, packaged, identified and taken to the Laboratory of Soil Chemistry – LABQLS at UEMA. While the data recorded by Arduino monitoring, were treated in Excel and transformed into graphs. The chemical analyzes of the material showed satisfactory values, mainly of Organic Matter available for the soil. Demonstrating that this process can be used for disposal and recycling of the tested residues, and that the monitoring of parameters helps in understanding the formation of the generated organic compounds.
