The Design of The Human Condition Detection System Based on STM32

The human body condition detection system designed by STM32 consists of MCU, power supply module, ECG module, skin electricity module, body temperature module, wireless transmission module and liquid crystal display module. The power supply module provides power for the whole system. MCU centralizes the calculation and processing of the data information in the whole system. ECG module collects the ECG signal of users through AD8232 chip. The skin electricity module collects the skin electricity signal through L324 chip. The body temperature module collects the temperature signal through NTC thermistor and displays ECG waveform and skin temperature value on OLED. Wireless transmission module communicates with intelligent terminal through CC2540 chip. Users can know their health status in real time. The system has the advantages of simple structure design, low power consumption and low cost, which makes the medical service more portable, personal and family-oriented.
