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.
Summary of project results
So far, there have been no portable sensors available on the market that can be used to 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.
Within the project, several novel sensing modules were built and tested, such as microwave NO2 gas sensors and optical particulate matter sensors with time delay integration technique. The main results of the project are the prototype platforms containing multi-pollutant sensing modules and communication devices for data transfer to the cloud, together with dedicated algorithms, models, and calibration procedures for improving the quality of AQ sensor measurements.
The HAPADS project designed and built novel air monitoring platforms including detectors, programmable devices, data acquisition, optimization models, and integrated air pollution calibration models. The low cost, compact HAPADS platform provides the possibility of a wide range of pollutant detection and autonomy, being suitable for mobile solutions that can be deployed on trucks, cars or buses. The proposed solutions should make it easier for end-users such as drivers, transport companies, municipalities and the public at large to make information-driven decisions to mitigate air pollution exposure.
Summary of bilateral results
The cooperation between the project partners was excellent during the whole project. Each of the partners thoroughly addressed the projectgoals, fully contributing to the HAPADS project. The Norwegian parents brought their huge expertise in managing large projects, as well asexcellence in air quality monitoring, resulting in improved understanding of the project material for all project partners. Norwegian work culturehad a positive impact on other partners as well. All the research conducted in the project was coordinated by the Norwegian partners, which wasvery helpful in maintaining results-oriented focus. The benefits of the bilateral cooperation resulted in the extension of cooperation in newprojects. For example, a joint application to the Horizon program was submitted, but was unfortunately rejected. However, there are plans tosubmit proposals to future funding programs in order to continue the works started in HAPADS project.
