This article presents a comprehensive literature review on the current state of automated monitoring and control in composting processes, with a particular focus on the integration of microcontrollers, gas, temperature, pH, and humidity sensors, as well as development boards. The main objective is to analyze and compare recent studies related to the development of automated composting systems.
The methodology employed consisted of a systematic review of the most recent scientific literature, in which multiple studies that have developed and implemented automated systems for monitoring and controlling composting conditions were analyzed. Various technological approaches were examined to identify trends, benefits, and challenges in the application of these tools.
The research findings showed that the use of controllers enables the continuous collection and processing of critical data, significantly improving the monitoring of key variables in the composting process. The importance of gas sensors—particularly those designed to measure carbon dioxide—was emphasized due to their role in assessing microbial activity and process efficiency. Likewise, temperature and humidity sensors were highlighted for their relevance in maintaining optimal conditions for the decomposition of organic matter. However, gaps in the literature were identified regarding the efficient integration of multiple sensors and the long-term evaluation of their impact on the final quality of the compost.
The conclusions underscore that, although technological advancements have enabled increasingly sophisticated composting automation, there are still challenges to be addressed. Future research is recommended to deepen the integration of multiple monitoring parameters and to analyze their influence on the physicochemical and biological characteristics of the produced compost. This study reaffirms the potential of these technologies to transform composting into a more efficient, controlled, and sustainable process, with relevant applications in both urban waste management and agricultural production.
