Smart Environmental Sensing Web comprises crowdsourcing and crowdsharing built on its existing IoT-based environmental monitoring system. This Smart Environmental Sensing Web includes continually expanding Micro Environmental Sensors, an environmental quality sensor networking platform, an Environmental Info Push application for smart phones, and an i-Environment website. Combining environmental sensing data from different sources through common transmission protocols and Open Geospatial Consortium (OGC) Standards, we used data visualization technology and location-based services to design graphical dashboards and interactive maps enabling users to access real-time local environmental information at any time, while also adding a convenient notification function that sends alerts when needed.
