Using low-cost sensors to monitor indoor, outdoor, and ...

With this in mind, we conducted a pilot study at six homes in Beijing, China, over 12 days to evaluate the use of portable, low-cost, time-resolved monitors for measuring O 3 indoors and outdoors. We also assessed personal exposure for one adult in each home for two 48 hour periods using backpack-mounted monitors. Prior to and following sampling we collocated all monitors with a reference analyzer; we …

Electrochemical ozone sensors: A miniaturised alternative ...

· 1. Introduction. Ozone sensors are a technology for O 3 detection that are characterised as being compact in size, low cost, low power and fast response. Most commercially available O 3 sensors use either electrochemical sensing principles or are based on semiconductor O 3 sensors. Such O 3 sensors have in principle sufficient sensitivity to be used in the ppb-range as air quality monitors for ...
