OxyPulse Alert System

The OxyPulse Alert System is a non-invasive IoT device that provides real-time monitoring of blood oxygen levels (SpO₂) and heart rate, particularly for chronic and high-risk patients. Globally, over 262 million people suffer from asthma and 3.5 million die each year from COPD—the 4ᵗʰ leading cause of death. This problem is expected to worsen as the elderly population is projected to grow to 2.1 billion by 2050. In Malaysia, 71% of deaths are from chronic diseases. Among older adults, 51.1% have hypertension, 27.7% have diabetes, and 41.8% have high cholesterol. It addresses this issue using a photoplethysmography sensor with red and infrared LEDs and a photodiode. It calculates SpO₂ from light absorption and tracks heartbeat. A Wemos D1 R1 microcontroller uploads data to Google Sheets, making it easy for doctors and caregivers to access from anywhere. The system uses built-in rules to detect danger signs like SpO₂ < 90%, heart rate > 100 bpm (tachycardia), or < 60 bpm (bradycardia), and immediately sends alerts through a Telegram bot. The design focuses on being affordable, reliable, and easy to set up—using Wi-Fi, low-cost parts, and minimal maintenance. It fits well into home or hospital use, reducing nurses’ workload and increasing patient confidence. With Malaysia’s digital health market expected to reach USD 834.2 million by 2028, it has strong business potential. It can grow through partnerships with insurers, healthcare providers, and tech firms. By combining real-time monitoring, cloud storage, and instant alerts, it helps detect problems early, reduce costs, and improve the lives of those at risk.
