Performance comparison between electrochemical and semiconductors sensors for the monitoring of O3

Abstract

As part of the Quality of Life and Urban Mobility (MouVIE) Chair, an individual mobile sensor designed as an adaptable and scalable "platform" is being developed within the LATMOS (Atmospheres Space Observations Laboratory). This sensor must contribute to answering problems related to the exposure of individuals to air pollution and their impact on health. In this context, its adaptable and scalable nature will allow the insertion of new consumer measurement components available ("low cost" micro-sensors). In this paper we present a laboratory evaluation of commercially sensors for the monitoring of ozone (O3). Two type of sensors are tested: electrochemical and semiconductors sensors. Theses sensors are tested at different temperatures, humidity and at ppb level. The voltage response and their dependence on ambiant temperature and humidity are evaluated. The time drift effect on electrochemical sensors was also evaluated during 4 months of use.
