NOVELTY - A fermentation monitoring apparatus includes environmental-condition sensors which measure environmental conditions in compost production chamber; quality sensors which measure the quality of the compost; a host server; input/output modules which collect the measurement results from the corresponding sensors; and panel computers for obtaining parameters stored in the host server.    USE - As a fermentation monitoring apparatus for a compost producing system, which produces the compost by fermenting organic plant and animal residues.    ADVANTAGE - The inventive fermentation monitoring apparatus allows for production of excellent compost in a short time by always measuring the environmental conditions and the quality of the composed being produced.    DETAILED DESCRIPTION - A fermentation monitoring apparatus for a compost producing system comprises environmental-condition sensors (121a-121e) which measure environmental conditions in a production chamber where compost is fermented. Quality sensors (121f, 121 g) are provided which measure the quality of the compost. A host server (111) is provided which stores parameters for controlling the environmental conditions in the production chamber. Input/output modules (122a-122c) are provided which collect the environmental-condition measurement results and quality measurement results from the corresponding sensors. Panel computers (116a, 116b) are provided for obtaining the parameters stored in the host server. The panel computers control the environmental conditions in the production chamber on the basis of the environmental-condition measurement results and/or quality measurement results collected by the input/output modules.
