A Low-Cost IoT-Based Smart Health Monitoring Band Using ESP32 and MQTT for Real-Time Health Tracking

The proposed IoT-based smart health monitoring band successfully demonstrates a low-cost, real-time, and efficient healthcare solution using ESP32 and MQTT communication. The system is capable of continuously monitoring vital parameters such as heart rate, body temperature, and motion, and transmitting the data to a cloud platform for remote access and analysis. The integration of multiple sensors with a dual-core microcontroller ensures reliable performance and low-latency response. The use of MQTT protocol provides efficient and lightweight communication, making the system suitable for real-time IoT applications. The wearable design enhances portability and enables continuous health tracking in daily life. Experimental results confirm that the system delivers stable performance with acceptable accuracy and minimal delay. The inclusion of an alert mechanism further improves user safety by providing immediate notifications during abnormal conditions. Overall, the developed system offers a cost-effective, scalable, and intelligent solution for modern healthcare monitoring. It has strong potential for applications in remote patient monitoring, fitness tracking, and smart healthcare systems.
