Abstract

A DUAL OPTICAL PATH SENSOR MODULE The present invention discloses a dual optical path sensor module for collect human 5 physiological signals based on photoplethysmography . T he module includes a base , and a photoelectric receiver and two light source modules mounted on the base . T he t wo light source modules are symmetrically disposed on two sides of the photoelectric receiver , and e ach source includes source s with at two ngths . A light shielding portion is further disposed on the base , the light shielding portion surrounds the 10 photoelectric receiver , and there is a n opening at the top of the light shielding portion, so that light emitted from the light source is received by the photoelectric receiver after the light is diffuse ly reflected by the human body tissue.
