Wing mirrors not the same?!

[LRTom]

Evening all!

On my passenger wing mirror I've got a little node that pokes down from the underside, what is this?
But on the driver side I've just got a little hole.

Normal?

Cheers!

i have one, used to be only on the passenger side, after i replaced the drivers side, that one has one too... wierd.

ext air temp sensor

boyz ....dont remove it ....lmao


its your external temperature guage for when your display will indicate how cold/warm its is outside , normally on the passenger side

i did wonder about it but didnt fancy tampering with it.lol

 

[f0xy]

wonder which one mine takes a reading from now then, both are wired into the connections of the wingmirrors :s

Cool, cheers for that, a bit of a poor place though a surely wind speed will affect temperature?

Presumably you failed science at school?

How fast air is or isn't flowing past a person affects how cold they feel because they sweat, and wind causes sweat to evaporate, and when it evaporates it has to absorb heat from the skin, and that's what the person feels.

How fast air is flowing past a car radiator affects the temperature of the water in the radiator because that water is above air temperature and more air flowing through the radiator can carry more heat away.

But how fast air is or isn't flowing past a sensor doesn't affect its reading because it isn't covered in sweat and isn't try to shed heat, its just trying to measure temperature.

How do you measure wind tempreture ?

Like on the weather forecasts or is is just estimation ?

haha, I did Physics A level and got a B! O well, you forget a lot Cheers for clearing that up!
