SYSTEM FOR ASSESSING AIR QUALITY

摘要

System for assessing the presence of gases and physical components in air, comprisinga number of different sensors, each sensitive to one or more different gases and/or physical components and each able to supply a signal varying with the concentration of the respective gases or physical components concerned, and means for processing the signals supplied by said sensors. Said processing means are embodied as a neural network to which the sensors are connected, in which all sensor signals are combined into one single output value, which network is adapted and programmed during a learning period in which the output value obtained for predetermined air samples is repeatedly compared with a similar value supplied by a reference panel of trained human beings or animals for the same air samples until both values are within a predetermined margin identical.
