Integrating multiple sources of Hong Kong air pollution data for the investigation of and decision-making on urban air pollution.
Air pollution has become a life-threatening hazard that exerts a serious impact on the sustainable development of our cities. The measurements from stationary ground-based stations are relatively costly and they are generally too sparse to build a complete and accurate picture of air pollution.
We have developed an Air Pollution Decision Support System (APDSS) that puts together all relevant multi-scale and multi-source data for the investigation of and decision-making on urban air pollution. We have also developed a compact Modular Sensor System with expandable plug-and-play sensor modules and multiple Wireless Sensor Networks compatibility.
Uniqueness and Competitive Advantages:
- APDSS is the first system to amass and integrate multiple sources of air pollution data in Hong Kong
- Our specially designed sensor node allows measurement of multiple pollution and weater variables at the same time
- The modularized sensors are equipped with configurable sensing capability, Plug-and-Play function, and support multiple wireless communication links
- Depending on different needs, the Modular Sensor System can be made wearable, stationary or vehicular
- The system is applied to the Community Weather Information Network (CoWIN) jointly hosted by IOFC, Hong Kong Observatory and Hong Kong Polytechnic University with over 100 secondary schools, collecting various kind of weather information in the community
