Air pollution is a global issue which has negative impacts not only on the environment but also on human health. Therefore, it is important to design and implement systems to allow cities and villages to monitor air quality so that they take the required actions to maintain a good air quality in the city/village. Since IoT facilitates implementing efficient monitoring systems, many IoT systems have been proposed to monitor air pollution. In this paper, we review different IoT-based systems to monitor air quality. In addition, we do an experiment where we propose and evaluate our system to monitor air pollution in a smart village, Veberöd, utilizing the LoRaWAN and the IoT platform, Yggio, which is already used in the village. Our proposed system is used to monitor temperature, humidity, pressure, PM1, PM2.5, PM10, CO2, and CO. As a result of our experiment, we found that the data received by Yggio was encoded, and Yggio did not provide the decoding functionality to decode the data sent from our devices. Therefore, another IoT platforms were used to decode, visualize, and analyse the data. The results of the experiments shows that as far as PM1, PM2.5, PM10, and CO are concerned, the air quality in the village is good. The results also showed that some LoRaWAN messages were lost and never received on Yggio.

Utvecklingen i samhället går i riktning mot att glesbygden avbefolkas, serviceställen och fysiska servicepunkter försvinner. Detta är något som påverkar landsbygden mycket. Denna studie syftar till att beskriva hur en digital transformation i form av en digital butik påverkar ett litet samhälle i Norrland. Studien är en undersökande studie med en kvalitativ metodologi, analys och datainsamling. De teoretiska referensram som ligger till grund för studien och som används i analysen är digital transformation, digitaliseringsstrategi, smarta byar och den digitala klyftan. De slutsatser studien kommer fram till är att införandet av en digital lösning har lett till framtidstro, förenklat vardagen samt gett en mer levande glesbygd. Genom digitaliseringens möjligheter har man hittat en lösning som är ekonomisk gångbar. / Developments in society are moving in the direction of depopulation of sparsely populated areas, and the disappearing of service points and physical service points disappearing. This is something that affects the countryside a lot. This study aims to describe how a digital transformation in the form of a digital store affects a small community in the most northern part of Sweden, Norrland. The study is a research study with a qualitative methodology, analysis and data collection. The theoretical frames of reference that form the basis of the study and that are used in the analysis are digital transformation, digitization strategy, smart villages, the digital divide. The conclusions of the study are that the introduction of a digital solution has led to hope for the future, simplified everyday life and provided a more vibrant sparsely populated area. Through the possibilities of digitalization, a solution has been found that is economically viable.
