The temperature and humidity sensor chip is applied in rainfall sensor products to detect raindrops on the front windshield, automatically activate the wipers based on the intensity of the raindrops, and dynamically adjust the frequency of the wipers. Some customers also integrate temperature and humidity sensors into the "five in one sensor module" inside the car cabin, which can detect the temperature and relative humidity of the inner surface of the front windshield, and calculate the dew point temperature. The air conditioning system adjusts the temperature and air outlet of the car's air conditioning system based on the temperature, humidity, and dew point temperature signals for defogging.
