How accurate are car outside temperature readings?
Therefore, if a car is parked on asphalt or concrete, the temperature you read is much warmer than what you will see if parked over a grassy or shaded surface. According to the Lawn Institute, “temperatures over turfed surfaces on a sunny summer day will be 10-14 degrees cooler than over concrete or asphalt.”
How does a car outside temperature sensor work?
