Low-cost sensors for indoor air quality : performance assessment in laboratory conditions

Abstract : The availability of low-cost sensors for real-time measurement of indoor air quality (IAQ) is increasing over the years for the general population. If their functionalities are very promising, there is still a need to evaluate their metrological performances. This can be achieved in the field by collocating the sensors with reference instruments. Laboratory experiments offer the opportunity to assess the steady-state response of sensors in a controlled environment.
