Abstract:

This study describes Amihan’s Breath, an Internet-of-Things–based air quality management system using Arduino R4 Wi-Fi that monitors and regulates indoor air quality (IAQ) in Davao City. The system measures 12 air quality and thermal parameters, including PM1.0, PM2.5, PM10, NOx, CO, O?, NH?, VOCs, temperature, and humidity, and provides real-time monitoring, alerts, and air-filtering functions. Sensor accuracy ranged from 97–100% before and after filtration. Initial IAQ analysis indicated moderate pollution levels, with PM10 averaging 85.64 µg/m³ and NOx averaging 96.89 µg/m³. After filtration, pollutant levels significantly decreased, including a 29% reduction in NOx and substantial reductions in particulate matter. Overall, Amihan’s Breath is an effective and cost-efficient IAQ management system recommended for high-risk environments such as schools and healthcare facilities.
