How to select an ambient light sensor

recent research shows that in a laptop, the battery power consumed by display backlights accounts for 33%. Sensing ambient light is not a new concept, but unlike photosensitive diodes, sensor sensing of ambient light can reduce excess infrared light and ultraviolet light while sensing ambient light, moreover, these fe
