Indents/Protrusions Under the Windshields of Vehicles

These are the things we can’t understand Sometimes it is circular, sometimes it sticks to the surface and sometimes it is flush with the surface.. Their shapes vary depending on the vehicle, but they are definitely there.

Alright What are these indentations or protrusions and what do they do?

Often these circular indentations or protrusions are actually solar load sensors.

Often to a removable plate, speaker grille, or defroster vent. is mounted. It is largely located on both sides of the instrument panel, again to accommodate differences in daylight exposure.

Alright “Why are they under the windshield of vehicles and not anywhere else?” If you ask, the purpose of this is is to detect how much sunlight enters the vehicle. Additionally, the solar load sensor is part of the climate control system.

Again, this sensor tracks the intensity of sunlight.

Additionally, to increase the comfort level of the driver and passengers on sunny days. heating, ventilation and air conditioning control settings.

Even in bright sun conditions, increase fan speed and open doors to improve cooling It may even cause

On the other hand, these sensors work by using photodiodes, which are active circuit elements that are sensitive to light energy.

A semiconductor diode that converts photon radiation may also be sensitive to infrared, X-rays, and gamma rays. But As the light intensity increases, the resistance of the diode increases. and ultimately fewer volts reach the vehicle’s internal monitoring systems from the sensor.

In summary, it is not a coincidence that solar load sensors are added under the windshields of vehicles. Also, if these sensors did not exist, Your car could absorb 2x more heat And as a result, it would be inevitable for you to encounter various problems in your vehicle.
