However, challenges remain in terms of energy consumption. In this paper, we assessed the impact of environmental variables in AVC based on the most influential variables. We developed an adaptive sampling period method to save IoT device energy and to maintain the ideal sensing quality based on these variables, particularly for temperature and humidity monitoring. The evaluation on real scenarios (Coffee Crop) shows that the suggested adaptive algorithm can reduce the current consumption up to 11% compared with atraditional fixed-rate approach, while preserving the accuracy of the data.pdfeninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Internet of thingsEnergy efficiencyAgricultura value chainColombiam coffeinfo:eu-repo/semantics/articleRodríguez, Carlos David; Rivas, Guillermo; Zerbini, Carlos; Ruiz Rosero, Juan; Ramírez González, Gustavo; Corrales, Juan Carlos.https://creativecommons.org/licenses/by-nc-nd/4.0/
