In the field of lighting, the phone uses the ambient light sensor to measure the amount of lighting in the “lux” unit, which is useful for photographers and interior designers. As for noise monitoring, the built-in microphones measure sound levels in decibels to assess sound pollution in the environment.
With regard to temperature, some models support sensors to measure weather temperature and external humidity, in addition to measuring the temperature of the processor and battery internally, which provides the user with accurate climate readings of his immediate surroundings, and turns the phone into a mini scientific laboratory capable of analyzing the environment.
