REFLECTIVE OPTICAL SENSOR MODULE

摘要

The present disclosure relates to a bi-directional reflective optical sensor module, an optical sensing accessory, and an optical sensing device. A bi-directional reflective optical sensor module (5) comprises a light source (110) and a first encapsulant (111), two photodetectors (120) and two second encapsulants (121), and a substrate (140). The bi-directional module emits light and detects light from two directions so that the light can be detected from different parts of a body. The optical sensing accessory and the optical sensing device comprise the bi-directional reflective optical sensor module and other electronic modules to have further applications.
