Optical sensor of harmful air impurity concentration

It is shown that to solve the problem of ensuring acceptable sanitary conditions in livestock premises while minimizing energy costs, it is advisable to use an automated exhaust ventilation system with control over the contour of the allowable concentration of harmful atmospheric impurities. The proposed block diagram of the sensor concentration of harmful impurities in the air, suitable for operation in conjunction with an automated ventilation system. Its mathematical model and transformation equation are obtained. It is shown that in the measurement range, which corresponds to the change of controlled impurities in the range from zero to the maximum allowable concentration, the static characteristic of the proposed sensor can be approximated by a linear function without significant additional methodological error.
