Abstract

The present disclosure relates to an optical sensing module, a system and a method for operating the optical sensing system. The optical sensing module includes a light emitter that emits a sensing light in a specific wavelength range and a photodiode unit. The photodiode unit includes a first photodiode used to sense a first wavelength light, a second photodiode used to sense a second wavelength light, and a third photodiode used to sense a third wavelength light. The optical sensing module implements a proximity sensor by operations of the second photodiode and the third photodiode, or a biometric sensor by operations of the first photodiode, the second photodiode, and the third photodiode. The photodiode unit receives a reflected light from an object to be detected so as to determine if the object is proximal, and then determine whether or not the proximal object is human skin.
