Hardware Introduction
SpO2 module
COMEN SpO2 Masimo SpO2 Nellcor SpO2
SpO2 board realizes SpO2 signal acquisition, amplification simulation, relative digital-to-analog conversion
and signal processing.
During the monitoring process, the pulse amplitude of the optical signal changes. Through calculation, the
SpO2 parameters, pulse rate signal and pulse width waveform are obtained. These data will be
transmitted to the main board and displayed on the screen.
