Thermometrics Dual Solar Sensor uses two photo diode cells to measure the intensity of the light that enters into the cabin of the vehicle. It then takes this information and feeds it back to the automatic temperature control (ATC) unit of the vehicle's air conditioning system. The air temperatures of the driver's side and passenger side are then automatically adjusted up or down depending upon the amount of light entering both sides of the vehicle.
The sensor is mounted on the IP panel near the vehicle's front window.
