This paper presents a standalone and wearable lung performance and real-time air quality monitoring system for patients with acute, chronic respiratory diseases. We have designed and implemented a multimodal Smart Chronic Health Monitoring Tool (SCHMT) consists of peak flow meter (PFM), NO2, SO2, O3, Particulate Matter (PM0.5-10), body/environment temperature sensors, microprocessor, and GPS units. The proposed SCHMT helps understand the impact of air quality on patients with chronic lung diseases and finds the gap between chronic patients and the healthcare system. The performance of SCHMT is measured and presented in this work.
