Combined sensors are designed for measuring indoor air quality, where they allow the measurement of several physical variables simultaneously. According to the measured values of the monitored variables it is then possible to control ventilation units.
Advantages of of the combined air quality sensors is the very simple and economically inexpensive installation in air distribution systems.
The combined sensors simultaneously measure carbon dioxide concentration, volatile organic compounds (VOCs), relative humidity and ambient air temperature in various combinations. A single sensor can more comprehensively determine the state of indoor air quality. The advantage of combined sensors is therefore to reduce the number of technical elements in the application, which also meets the requirements of architects.
Combined sensors are offered in the following variants:
