In this thesis we discussed the process system for controlling air quality in rooms. In this, we focused on the sensor measuring system, which enables the control of air quality from the point of view of dust particles and the measurement of concentration; oxygen, carbon dioxide, carbon monoxide and nitrogen oxides. We developed and produced a process control system for the quality of air in the space, with which we performed comparative analyzes in different environments. The measured results show the actual, current state of the air and the pollution of dust particles in the room. The last section shows a comparison of all measurements and directions of possible system upgrades.
