Circuit / System Description
The ambient light/sunload sensor integrates the sunload sensor and passenger compartment temperature sensor.
This sensor assembly provides information about:
Sun heat intensity
Passenger Compartment Temperature
The solar sensor is connected to ground and to the 5?V stabilized voltage supply through the HVAC control module. As the sunload increases, the sensor signal voltage also increases and vice versa. The signal varies between 1.4-4.5?V and is provided to the HVAC control module.
The passenger compartment temperature sensor is a negative temperature co-efficient thermistor. A signal and low reference circuit enables the sensor to operate. As the air temperature increases, the sensor resistance decreases. The sensor signal varies between 0-5?V.
Bright or high intensity light causes the vehicles interior temperature to increase. The HVAC system compensates for the increased temperature by diverting additional cool air into the vehicle.
