Studies for every level of CELSS: Waste processing, food production, photosynthesis system, and so on ..., imply an automatic system to control, command and quantify gases, water and chemical compounds. Used for many years in plant physiology studies, the C23A system monitors the analysis and quantifies gases (O2, CO2. N2, ...), physical parameters (temperature, humidity, ...) and chemical compounds (NH4+, N03-, ...) on numerous experiments. In the new version, the architecture of the computing system is near of the space requirements. We have chosen a structure with three independent levels: acquisition, monitoring and supervision. Moreover, we use multiplexed analysers: IRGA, mass spectrometer and cheminal analyser. The multiplexing increases the accuracy of the measurements and could facilitate the spatialization. Thus the whole structure anticipates the entire separation between automation in space and control-command on ground.
