In-Vehicle Temperature and Humidity Sensor

The in-vehicle temperature and humidity sensor contains a thermistor and a sensing element which separately measure the in-vehicle air temperature and humidity and sends those readings to the Heating, Ventilation, and Air Conditioning (HVAC) module. The in-vehicle temperature and humidity sensor has an electric fan within the sensor that draws in-vehicle air across the two sensing elements.

The humidity sensor is used by the Heating, Ventilation, and Air Conditioning (HVAC) module to optimize the Air Conditioning Compressor Module (ACCM) operation for reduced electrical system load while maintaining passenger comfort.
