A wireless device for human physiological parameters is designed by using max31002, the device is STM32 series microcontroller as the core, through the MAX30102 model using photocapacity pulse description method (PPG) to collect the pulse wave signal of the index finger ending artery, and then the source signal digital filtering processing and scale conversion, to obtain blood oxygen and heart rate measurements, and can communicate with the mobile phone Bluetooth. By calibration comparison, the measurement range of blood oxygen saturation is 35% to 100% (the blood oxygen saturation of normal human arterial blood is 98%), the resolution is 1%, the accuracy is 70% to 100% ± 2%, less than 70% is undefined, and the pulse charge is 0 .4%, can correctly show oxygen saturation, heart rate measurement range of 0 to 150 times/minute (adult normal heart rate of 60 to 100 times/minute), the error is not more than 1%, the temperature range 0 to 50 ℃, the resolution of 0.1 ℃, the error is not more than 0.2%.
