LOW POWER NDIR-CO₂-SENSOR FOR BUILDING AUTOMATION

Michael Gürtner, Norbert Neumann, Friedrich Schneider

Abstract

Besides humidity the content of CO₂ is the most important air quality parameter in private homes. On the other hand power consumption for heating and air conditioning contributes essentially to the worldwide energy problems. An effective way to reduce it is to develop decentralized air conditioning systems consisting of optimal matched components. A major component is the air quality sensor which has not only to acquire CO₂ but also humidity and temperature. Further on such a sensor needs powerful data processing features and an interface to a bus system (either by TP or RF). The design requirements for it are different to those for sensors in industrial applications. Main targets are reliability, no maintenance and no recalibration for several years, low power consumption, small size and reasonable costs rather than high precision.
