car outdoor thermometer

[Ghost~Rider]

Hi, How does a car give an air temperature reading for outside please? I always thought that the wind caused by the car moving would make the temperature colder. Thanks.

the sensor is behind the bumper,out of the wind, although even there I would have though it would suffer from "wind chill".

The human body produces its own heat. In perfectly still air, that heat is only lost very slowly. In rapidly moving air, body heat is lost much faster. So the human body suffers from 'wind chill' when sensing temperatures. (i.e. for the same air temperature, it will feel much colder in a strong wind than in still air)

Thermometers (of whatever type) don't produce heat, so they can't lose heat. They simply respond to the temperature of the surrounding air. It doesn't matter whether the air is stationary or blowing a gale; a thermometer only 'feels' the real temperature of the air. (i.e. thermometers don't register wind chill).

as stated, wind chill is only applied to living creatures.
a mechanical device shouldnt register a colder temperature simply because its moving.
an example would be aeroplanes. moving at 500mph would give a wind chill of -100s of degrees but the temperature is registered as a true temperature.
