    Abstract: There is provided a smoke detector including a first light source, a second light source surface, a light sensor and a processor. The light sensor receives reflected light when the first light source and the second light source emit light, and generates a first detection signal corresponding to light emission of the first light source and a second detection signal corresponding to light emission of the second light source. The processor distinguishes smoke and floating particles according to a similarity between the first detection signal and the second detection signal.

    Abstract: A physiological detection device includes system including a first array PPG detector, a second array PPG detector, a display and a processing unit. The first array PPG detector is configured to generate a plurality of first PPG signals. The second array PPG detector is configured to generate a plurality of second PPG signals. The display is configured to show a detected result of the physiological detection system. The processing unit is configured to convert the plurality of first PPG signals and the plurality of second PPG signals to a first 3D energy distribution and a second 3D energy distribution, respectively, and control the display to show an alert message.

    Abstract: A wearable device includes a case and a far infrared temperature sensing device. The case has a first opening. The far infrared temperature sensing device is disposed inside the case of the wearable device. The far infrared temperature sensing device includes an assembly structure, a sensor chip, a filter structure, and a metal shielding structure. The assembly structure has an accommodating space and a top opening. The sensor chip is disposed in the accommodating space of the assembly structure. The filter structure is disposed above the sensor chip. The metal shielding structure is disposed above the sensor chip, and has a second opening to expose the filter structure. The first and second openings are communicated to cooperatively define a through hole.
