RnMonitor: a WebGIS-based platform for expedite in situ deployment of IoT edge devices and effective Radon Risk Management

RnProbe: A LoRa-Enabled IoT Edge Device for Integrated Radon Risk Management

“…Two distinct laboratories of the School of Technology and Management of the Polytechnic Institute of Viana do Castelo, i.e. L 1.11 and L 3.5 respectively have been continuously monitored using the IoT edge in parallel with the RnMonitor Platform [34]. L 1.1. is situated on the ground floor and Lab 3.5 is located on the third floor of the building.…”

“…It was specified to compute a set of metrics and KPIs for distinct time periods: Real-Time (last hour), Very-Short-Term (last day), Short-Term (last 7 days), and Long-Term (last year), based on specific building occupancy profiles. More details on the cloud/analytics engine can be found in [34]. 3) Client App/Dashboard: this block is responsible for data visualization and user interaction.…”

“…By selecting a specific entity (building, room, or device), a customized dashboard is rendered, showing the relevant metrics and KPIs that were previously defined for radon management in a specific spatiotemporal context. This block is described in more detail in [34].…”

Towards a Smart & Sustainable Campus: An Application-Oriented Architecture to Streamline Digitization and Strengthen Sustainability in Academia

“…On the other hand, a time-series database was installed in the server, to store and manage the data collected by the IoT Devices after decoding from Base64 to directly connect to a Grafana as-a-service, a user-friendly open-source dashboard technology. More information about the cloud/analytics engine can be found in [26]. Figure 5 displays the map-centered front-end interface, containing two features defined as layers-Sensors and Polygons, that is represented by the color associated with the Radon Risk Indicator, colors which range from Green-Safe to Yellow-Warning, Orange-Alert or Red-Critical, triggering notifications via sockets to the device responsible and/or owner [25].…”

“…• Monolithic: single application component containing all the application's functionality, and mixing components' roles like data persistence, business logic, or user interface, e.g., [26,38]; • Layered (or N-tier) architecture: several application components organized in rolebased layers, e.g., [17,28,30]. Typically, the top layer includes only components that deal with the user interface and the bottom layer has the components that deal with data persistence, one or several middle layers or tiers deal with the business logic at different levels of abstraction.…”
