This paper conducts an analysis and comparison of air quality in diverse settings, spanning indoor and outdoor environments. The objective is to identify avenues for improving well-being and informing larger organizations about essential monitoring priorities for optimal breathable air. The paper comprises three core sections. The initial segment focuses on air quality analysis and the utilization of sensors for indoor and outdoor measurements. The subsequent part elaborates on data transmission via the LoRa Wan protocol, utilizing an ST gateway and end nodes to relay analyzed data for centralized processing, with a particular exploration of LoRa transmission ranges in urban areas. The final section outlines future developments and key investigations using various sensors.
