Is the Outside Temperature Displayed in Cars Accurate?
1 Answers
Car displays the outside temperature accurately. Here are the relevant details: 1. Temperature: The outside temperature displayed by the car is accurate. For example, when the car dashboard shows a low outside temperature, it is indicated by a snowflake symbol, which serves as a reminder for the driver to be cautious of icy road conditions and drive carefully. This alert typically appears when the outside temperature drops below 4 degrees Celsius, as drivers may not sense the external temperature changes inside the vehicle. 2. Principle: The outside temperature sensor generally operates using an NTC thermistor to measure temperature. NTC stands for Negative Temperature Coefficient, meaning the resistance decreases as the temperature increases.
