Design and Development of Wearable ECG-SpO2 Monitoring System with Cloud-Based Alert Da...

Objective: To engineer a low-cost wearable device for continuous ECG and SpO2 monitoring with real-time cloud data visualization and automated abnormality alerts.

Cardiovascular diseases and respiratory disorders are leading causes of morbidity and mortality in India, especially in rural and elderly populations lacking access to regular medical monitoring. Early detection of abnormal heart rhythms or blood oxygen levels can prevent serious complications, but continuous monitoring devices are often expensive or unavailable in many regions.

This project proposes the design and implementation of a compact, battery-operated wearable device that captures single-lead ECG and SpO2 data, transmits it securely to a cloud dashboard, and triggers SMS/email alerts on detection of abnormalities. The system leverages open-source embedded platforms (such as ESP32), medical-grade analog front-end sensors (e.g., MAX30102 for SpO2, AD8232 for ECG), and integrates with cloud services using MQTT/HTTPS protocols.

Key deliverables include: a wearable prototype, real-time web dashboard for data visualization, threshold-based abnormality detection algorithm, cloud-based alert system, and validation of device accuracy against standard clinical equipment. The final demonstration includes a live user test, cloud monitoring, and simulated alert generation for examiner review.

Industry and societal impact: The solution addresses the need for affordable, scalable remote health monitoring in India, enabling early intervention, telemedicine integration, and potential deployment in rural health centers, elderly care, and post-operative monitoring. The modular architecture allows adaptation for other biomedical parameters.
