In-Vehicle Temperature And Humidity Sensor

The in-vehicle temperature and humidity sensor contains a thermistor and a sensing element which separately measures the in-vehicle air temperature and the humidity, then sends those readings to the HVAC  control module to adjust the actuator doors. The in-vehicle temperature and humidity sensor has an electric fan within the sensor that draws in-vehicle air across the two sensing elements. If the vehicle cabin becomes too humid the HVAC  control module adjusts the air inlet door to allow more fresh air. When the humidity level drops, it adjusts back to recirculated air.
