摘要: Abstract In this paper, monitoring of the composting process with an e-nose is presented. An emission chamber developed for purpose and put on a household waste compost pile. A lab-made metal oxide sensors located at exit chamber. Simultaneously to measurements, air sampling sorbent tubes as well physico-chemical analysis are realised. The adsorbed samples analysed in lab by gas chromatography coupled mass spectrometry (GC–MS). addition, some parameters collected (compost temperature, age pile, date aeration). Correlation between 14 chemical families determined principal component (PCA). By canonical analysis, two models calibrated proportion each family function events. Thanks these models, various kinds events possible only one measurement device.
