An integrated indoor air pollutant measurement and unified reporting system

Abstract

The utility model relates to an integrated indoor air pollutant measurement and unified reporting system that enables real-time monitoring of indoor air quality. The system comprises a plurality of Arduino-based sensor nodes provided with a particulate matter sensor, a gas sensor, and a temperature and humidity sensor, all electrically connected to a microcontroller configured to perform edge-level preprocessing of measured data. A gateway device receives the transmitted data, normalizes the readings, and executes data fusion to produce unified pollutant values. A unified reporting module generates consolidated reports and visual dashboards showing real-time pollutant indices, temperature, humidity, and alerts when thresholds are exceeded. The system provides a cost-effective, scalable, and interoperable solution for continuous indoor air quality monitoring and unified reporting across multiple sensing points without reliance on external cloud services.
