MY17 F-Type R

Just wondering what this is and why it's vented.
thanks

Pretty sure it is the Humidity Sensor. See blow for more info and what it does...

Humidity Sensor
The Humidity Sensor is installed in a bracket attached to the inside of the windshield, to the right of the interior
mirror. The sensor is concealed under a cover that clips onto the bracket.

The sensor comprises three individual elements:
• A capacitive humidity sensor
• An NTC thermistor air temperature sensor
• An infrared windshield glass temperature sensor
The Humidity Sensor is powered by a feed from the ignition
relay in the CJB. The data from the three individual
elements of the sensor are transmitted in LIN bus messages
to the ATCM. From the data, the ATC module:
• Adjusts the humidity of the air in the vehicle as
necessary, to provide the optimum comfort level
for occupants
• Calculates the dew point temperature of the air at
the inside of the windshield
Humidity within the vehicle is controlled by raising
or lowering the temperature of the evaporator. An
increase in evaporator temperature increases the moisture
content of the air at the windshield. Lowering the
evaporator temperature reduces the moisture content
of the air in the interior.
If the dew point of the air within the passenger compartment
rises to be close to that of the windshield,
temperature misting is likely to occur. To prevent this,
the ATCM will:
• Increase the blower speed
• Reduce the evaporator operating temperature to its
lowest safe running temperature
• Increase the temperature of the air leaving the
climate control assembly
• Adjust the position of the demist distribution motor
to direct more air to the windshield
• Adjust the position of the recirculation motor to
admit more fresh air
• Signal the CJB to energize the windshield heater (if
equipped)

thank you! Impressive list of everything it supposed to do😳
