Description
HAPADS is an ambitious project that will custom design and build a novel air mobile monitoring system (devices, data acquisition, analysis and user interface) which, will enable end-users (drivers, transport companies, municipalities and the at-large public) to make information-driven decisions to mitigate air pollution exposure for personnel and to the public. HAPADS will be a solution to overcome the significant problems of the use moveable and portable air quality MPs in mobile air quality monitoring. HAPADS will have special features: HAPADS be based on a mobile programmable platform for data collecting, processing, modeling and transmitting wirelessly. The proposed platform will integrate the sensors and transmitting devices, it will also extensively collect and process data.
To monitor gas such as NO2, HAPADS method is based on the dedicated nitrogen dioxide gas sensors developed with the utilization of metal oxides that serves as gas-sensitive materials. The measurement method will be based on the novel microwave circuits and conventionally resistive measurements to cover the full range of possible target gases concentration in comparison with commercially available NO2 detectors.
To monitor PMs, HAPADS methods are using direct particle counting of certain sizes allow precise and unambiguous measurements. The proposed sensor uses this principle to accurately measure PM.
Currently there are no portable sensors available on the market that use this measurement principle. The innovativeness of the proposed solution lies in the development of the first prototype using the principle of direct PM counting, which is small, cheap and can be used as a portable device.
HAPADS will devise and implement specialized embedded software for energy-efficient cognitive mobile MPs that are automatically self-calibrated for a new deployment location, enabling mobile deployment.
