Blood pressure measurement moduleThe measurement method is not yet understood by everyone. Below is a detailed introduction. Xinzhi Technology has developed a dedicated module for human blood pressure measurement, which is equipped with a "boost" blood pressure algorithm and air pump/valve control. Users only need to provide power to the module, and can directly obtain blood pressure measurement data or real-time pulse waveform through the module communication interface.
It can generally be applied to medical blood pressure measurement devices, multi-functional parameter detectors, wearable medical measurement devices, etc. All blood pressure measurement devices are based on high-speed and high-efficiency 8051 compatible microcontrollers, with a maximum main frequency of up to 24MkHz. The module contains 128K bytes of FLASH ROM, 8192 bytes of RAM, and 24 bits of ADC, which can be developed for secondary use
Built-in blood pressure algorithm, built-in adaptive air pump control algorithm, sleep power consumption: rated working voltage, shutdown current ≤ 20Ua, measurement range and accuracy: pressure range: [0-295mmHg (0-39.3kPa)], accuracy: ± 3mm Hg (± 0.4kPa); Pulse rate: 40-180 beats/minute, with an accuracy of ± 3%. Power supply voltage range: 2V-6V Communication interface: IIC, UART, SPI, working temperature range: 5 ℃ -40 ℃
