Indoor air quality (IAQ) significantly impacts health, yet many existing monitoring systems fail to integrate awareness into daily routines. We developed a smart lamp that combines lighting with real-time IAQ sensing. A Raspberry Pi collects data from three sensors— PMSA003I (PM2.5), SGP30 (VOC/eCO₂), and SCD-40 (CO₂, temperature, humidity)—and maps results to Philips Hue lighting states. Green, yellow, and red cues provide instant awareness, while a companion Flutter app with Firebase storage offers history, charts, and AI-generated recommendations [12]. Experiments showed that the lamp’s PM2.5 readings strongly correlated with a reference monitor and that users accurately interpreted color cues, especially when supported by the app. Compared to conceptual frameworks, smartphone apps, and other low-cost devices, our solution integrates awareness, understanding, and action more effectively. By embedding IAQ feedback into everyday lighting, the smart lamp offers an accessible, intuitive, and reliable approach to healthier indoor environments [13].
