An Embedded IoT Architecture for Continuous Output Pressure Surveillance in Medical Oxygen Concentrators

The increasing demand for portable and reliable medical oxygen delivery systems has highlighted the need for continuous monitoring of key performance parameters, particularly output pressure, to ensure patient safety and device efficiency. Traditional oxygen concentrators often lack real-time monitoring capabilities, making it difficult to detect pressure anomalies that may compromise therapeutic effectiveness. To address this limitation, a cost-effective, IoT-enabled monitoring system has been developed. The proposed system integrates a 1.2 MPa atmospheric pressure sensor with an HX710B analog-to-digital converter to accurately measure output pressure levels. An ATmega328 microcontroller processes the data and displays real-time readings on an LCD screen, while an ESP8266 module transmits the information to the Blynk cloud platform for remote access and data logging. This architecture allows healthcare providers and users to receive immediate alerts when pressure deviates from safe thresholds, enabling timely maintenance and minimizing risks. The system demonstrates stable performance, reliable wireless communication, and effective pressure monitoring. Its low cost, ease of integration, and remote accessibility make it well-suited for home healthcare, telemedicine applications, and smart medical device development.
