Ambient temperature sensor placement in a car

not a question, but just something i learned that might be helpful to others.

i placed the temp sensor in same spot as oem which is forward of the radiator, hidden but where it gets airflow.

i struggled with heatsoak from engine and hot asphalt when not in motion.

i changed my code to update only when it's either a down tick or when speed is it least 30 mph. works perfect, even better than some oem i've had.

And the opposite problem with rain, snow, sleet and hail.

where's it gain a bias? won't be a problem unless sensor is buried under snow accumulation which is a consideration with placement.
