Abstract

With the proliferation of Internet of Things (IoT) technology in the healthcare sector, health monitoring devices are rapidly transitioning towards portability and wireless connectivity to meet users' demands for heart rate monitoring in daily and exercise scenarios. Addressing the current opportunities for improved multi-scene adaptability and functional integration of portable devices, this paper presents a wireless heart rate monitoring system based on the ESP32 microcontroller. The system utilizes the MAX30102 PPG sensor for heart rate signal acquisition, leveraging the low power consumption characteristics of ESP32 and its built-in Wi-Fi module to accomplish local signal processing, real-time display on an OLED screen, and data interaction with a cloud platform via the HTTP protocol, forming a complete process of "acquisition - processing - display - transmission". Experimental results demonstrate the system's capability to consistently acquire and remotely synchronize heart rate data, making it well-suited for applications in home health management, exercise monitoring, and other scenarios. The comprehensive functionality aligns closely with user needs, showcasing high practicality and value for dissemination.
