Product Summary
CMOSens® Technology for IR detection enables carbon dioxide measurements of the highest accuracy at a
competitive price.
Along with the NDIR measurement technology for detecting CO
2
comes a best-in-class Sensirion humidity and
temperature sensor integrated on the very same sensor module. Ambient humidity and temperature can be
measured by Sensirion’s algorithm expertise through modelling and compensating of external heat sources
without the need of any additional components. The very small module height allows easy integration into
different applications.
Carbon Dioxide is a key indicator for indoor air quality. Thanks to new energy standards and better insulation,
houses have become increasingly energy-efficient, but the air quality can deteriorate rapidly. Active ventilation
is needed to maintain a comfortable and healthy indoor environment and improve the well-being and productivity
of the inhabitants. Sensirion sensor solutions offer an accurate and stable monitoring of CO
2
in the air, as well
as temperature and humidity. This enables our customers to develop new solutions that increase energy
efficiency and simultaneously support the well-being of everyone.
