In partnership with Southern University of Science and Technology (SUSTech), Chinaway delivered a university-wide Indoor Air Quality (IAQ) intelligence system comprising 120 portable devices: 72 CW-PPC300 particle counters and 48 CW-HTA200S PM2.5 testers. Units are deployed in rotation across 150 classrooms, 86 laboratories, and 32 dormitory blocks, with data uploaded daily to a custom cloud dashboard. Faculty and students access anonymized real-time metrics via mobile app; maintenance teams receive automated alerts when thresholds exceed WHO-recommended limits. Since deployment in March 2025, respiratory-related sick leave among staff decreased by 33%, and the university achieved Gold Certification under China’s Green Campus Evaluation Standard.
