IoT-Enabled Multi-Point Human Motion Monitoring System Using Sensor Multiplexing and Intelligent Inertial Measurement Technology

The IoT-Enabled Multi-Point Human Motion Monitoring System is an advanced healthcare monitoring solution designed to track and analyze human body movements in real time. The system utilizes multiple MPU6500 inertial measurement sensors strategically positioned on different body parts to capture acceleration, angular velocity, posture, gait, and motion dynamics. A PCA9548A I2C multiplexer enables simultaneous communication with multiple IMU sensors, while the NodeMCU serves as the central processing and wireless communication unit.

The collected motion data is processed and transmitted through IoT connectivity, allowing healthcare professionals, physiotherapists, and caregivers to remotely monitor patient activity and rehabilitation progress. The system can identify abnormal movement patterns, posture deviations, mobility limitations, and rehabilitation performance metrics.

Powered by a 3S lithium-ion battery pack, 3S BMS, and buck converter, the platform offers portable and reliable operation for continuous patient monitoring in hospitals, rehabilitation centers, elderly care facilities, and home healthcare environments.
