    Abstract: A biometric detection module including a light source module, a detection region and a control module is provided. The light source module is configured to emit green light, red light and IR light in a time division manner to illuminate a skin surface. The detection region is configured to detect penetration light emitted from the light source module for illuminating the skin surface and passing through body tissues to correspondingly generate a green light signal, a red light signal and an IR light signal. The control module is configured to determine a filtering parameter according to the green light signal to accordingly filter the red light signal and the IR light signal, and calculate a biometric characteristic according to at least one of the green light signal, a filtered red light signal and a filtered IR light signal.

    Abstract: An optical detecting module with waterproofing function can be installed on a housing of a wearable device and includes an optical detecting component, a light source and a packaging structure. The light source is disposed by the optical detecting component, and the packaging structure provides the waterproofing function to the optical detecting component and the light source. The packaging structure includes a main body, a light emitting unit, alight incoming unit and a waterproofing component. The main body covers the optical detecting component and the light source. The light emitting unit and the light incoming unit are disposed on the main body and respectively face the light source and the optical detecting component. The waterproofing component is filled into a gap formed between the main body and the housing, to prevent moisture from leaking into the gap to rust terminals of the optical detecting component and the light source.
