This paper addresses the critical need for personal air quality monitoring, focusing on CO2 exposure's impact on health [1]. Current solutions often lack portability and user-specific recommendations [2]. We propose CAIR, an electronic necklace with a mobile app, equipped with a CO2 sensor and microcontroller, to provide real-time air quality data and personalized health advice. Key technologies include advanced sensors, microcontrollers, and secure mobile communication. Challenges such as sensor accuracy and data privacy were mitigated through calibration and encryption. Applied in various scenarios, CAIR demonstrated reliable performance in monitoring air quality and providing actionable insights [3]. Our results indicate that CAIR effectively empowers users to manage their exposure to CO2, making it a valuable tool for enhancing personal health and safety in diverse environments. This innovative approach promotes greater awareness and proactive management of air quality, ensuring better health outcomes.
