基于AVR单片机的数字血氧模块的开发

Investigation of Digital Blood Oxygen Module with AVR Single-chip Microprocessor

利用光频传感器TSL235与8位AVR单片机MEGA8,开发小型的微功耗血氧模块,实现血氧饱和度和脉搏监护。该模块低功耗、弱灌注,具有良好的基线控制功能,可达到运动测量的目的。

A compacted module with low power consumption was investigated for the monitoring of blood oxygen saturation and pulse with TSL235 model light-to-frequency converter and 8-bit AVR single-chip microprocessor MEGA8.The module is suitable to the measurement under motion state with well designed base controlling and the character of low power consumption and low perfusion.
