Web Application for Displaying Results of Air Quality Measurement Using View Plus Radon Detector

View Plus Radon Detector made by Airthings is a device that allows measur- ing a number of parameters related to indoor air quality. The device has the ability to connect wirelessly to the Internet, where it is possible to monitor the measurement results later on a purpose-built online platform - Airthings Dashboard. The Airthings Consumer API enables downloading of measured values outside the Airthings Platform as well. This paper presents a web ap- plication that allows downloading data from the Airthings Consumer API and displaying them in a graphical environment. This web application was created using React.js, JavaScript, CSS and HTML. The solution presented in this paper is comparable to other studies results that offer similar functionalities. Similar solutions offer the possibility to monitor air quality parameters as well as our solution, taking into account the fact that hardware and software technologies are versatile and we have not found an identical combination of our hardware and software in other solutions. The display of results on the web offered by our solution is an approach that also exists in some other solutions. Mitigation and prediction are components that exist in some of the other solutions, and our goal is to enable our solutions with a support for these components.
