IoT-Based Health Monitoring Systems: A Comprehensive Review of Technologies, Applications and Challenges

Integration of Internet of Things (IoT) technology in the abstract healthcare system has enabled the development of real-time, distance health monitoring solutions. This article presents the design and implementation of the IoT-based health monitoring system that can track important signs such as body temperature, heartbeat, and oxygen level in the blood. The system uses sensors connected to a microcontroller, which transmits the data in a wireless way to the cloud platform for storage and analysis. Healthcare professionals and patients can access this data through a user-friendly mobile or network interface, which may enable the identification of nonconformities and timely medical intervention. The proposed system allows for continuous monitoring and healthcare analysis with platforms. This patient provides initial warnings and future insights into health trends. By generating useful information from real-time data, the system with active clinical decision-making in shifts against digital health services helps reduce hospital admissions and AIDS. The results show their reliability, scale capacity and current health informatics for integration into science systems.
