WebMar 5, 2024 · Two components make it work: 1) An infrared LED light (infrared is a color that is not visible to the naked eye) 2) A light sensor (covered with a translucent film to block most non-infrared light) When the emitter shines infrared light onto your skin, the sensor sees the light bouncing back. That's how it detects your face.
