A design of a home-based human health monitoring device with OneNET cloud platform

As the pace of life continues to accelerate, the issue of subhealth becomes an important topic and the study of human health monitoring receives more attention. Compared with traditional health monitoring devices, a portable and low-cost monitoring system is urgently needed to help people obtain their human health status. In this paper, we design a home-based human health monitoring system. The system uses an STM32 microcontroller as the main controller of the embedded system and four human signal acquisition circuits to collect human heart rate signal, ECG signal, blood pressure signal, and body temperature signal. After processing the data, the system applies a wireless module and uploads the health data to the OneNET cloud platform. The experimental results show that the system can accurately collect human physiological signals, and the error of heart rate signal is within 10 Bmp, blood pressure is within 10 mmHg, and body temperature is within 1.5°C compared with professional medical equipment. Finally, the health data is stored and displayed in real-time on the OneNET cloud platform.
