Design of wearable physiological information wireless monitoring system based on GPRS

In order to solve the problems of the present physiological information detection system such as the overuse of network communication, inconvenience of carrying and detection singleness of physiological information, the portable wireless physiological information monitoring system was designed in GPRS technology. The system was designed with STM32F030C8T6 MCU as core component. The MCU could read data measured by the sensors of body temperature, blood pressure and heart rate at fixed time, and then realize the wireless monitoring and transmission by serial port with SIM900A GPRS module. The system could realize message receiving and sending only through communication network, and it was portable and suitable for the monitoring of old solitary people.
