Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Description We discovered that it is possible to use cheap sensors intended for measuring high CO concentrations (<1000ppm) in environmental sensing applications that only have low concentrations (<20ppm). This process is not, however, trivial, because the sensors have cross sensitivities to other gases, to temperature, wind flow and humidity that can be difficult to control for.
Exploitation Route It would be possible (we have started initial discussions) to develop the system into an open source form, available for citizen science. This process is not easy if the desire is to obtain data of scientific quality, primarily because device calibration is not easy.

Description Our findings were published and, indeed, the process of publication is continuing. The low-cost sensing approach we took, coupled with work on calibration and data analysis is expected shortly to be discussed in a Nature article on air quality monitoring. Further development work on sensors for gas monitoring is continuing, and we have continued and expanded a collaboration established during the project to develop cheap sensors capable of detecting explosives and illicit drugs. This work is currently being carried forward within the NCA.
