Indoor and Outdoor Environmental Monitoring System through IoT based Embedded City Boxes (ECB)
Dec 2020

Project Video

The Embedded City Box (ECB) system, sponsored by Siemens, is a network of boxes equipped with a wide range of environmental sensors. ECBs can collect a range of real-time data on  environmental conditions, including temperature, humidity, noise and air pressure. For air quality monitoring, they also measure respirable suspended particulates, such as sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO) and ozone (O3). All data collected from the ECBs can be transmitted to a state-of-art IoT cloud platform called MindSphere – a highly secure cloud platform that facilitates the analysis of the data for smart city planning. The platform analyses and classifies the collected ECB data into different profile indexes. The profile index is presented on a dashboard showing the air quality condition in the monitored areas. Trend logging data, showing fluctuations in air quality over time, are also provided via MindSphere, helping to track pollutant concentration patterns in the areas being monitored.

The dots on the map shown in MindSphere’s Geographical View pinpoint the locations of the ECBs installed in IVE (Sha Tin), IVE (Haking Wong) and other Air Quality Health Index checkpoints installed by the Environmental Protection Department. Thanks to these ECBs and the MindSphere platform, much more comprehensive data on air pollution across the city can now be collected for further analysis, forming part of the construction of a Smart City.
