This paper addresses the critical need for real-time air quality monitoring through the development and implementation of the Air Pendent app and device [4]. Recognizing the escalating concerns surrounding carbon dioxide emissions, climate change, and indoor air quality, our solution integrates cutting-edge technology to empower users with immediate, personalized insights into their surroundings [5]. The challenges of interoperability, sensor accuracy, and community engagement were systematically addressed through experiments involving ten diverse participants. Results revealed high user satisfaction, consistent sensor accuracy, and varying community participation rates. While optimization for Android devices and cross-platform performance enhancements are recommended, the Air Pendent project emerges as a promising tool for fostering environmental awareness and community-driven solutions [6]. This comprehensive and user-centric approach provides a tangible means for individuals to actively engage with and positively impact their immediate environment, positioning the solution as an essential tool for a sustainable future [7].
