Abstract: A temperature and humidity sensor module sensing method for enabling a temperature and humidity sensor in an electric product to provide the detected humidity message to a micro control unit for determination. According to the characteristic curve of a known humidity sensor, the micro control unit determines that the humidity value rising slope exceeds a predetermined rising slope for a specific period of time, or the relative humidity rises a predetermined percentage for a specified period of time, or a high humidity limit continues for a specific period of time, indicating that the surface of the temperature and humidity sensor is attached or condensed with water molecules. Then, the micro control unit controls the heating element to heat-dry the temperature and humidity sensor, keeping the temperature and humidity sensor in the optimal working condition.

Abstract: A temperature and humidity sensor module heat drying structure used in an electrical product is disclosed to include a temperature and humidity sensor, a heating element and a micro control unit. When the humidity value detected by the temperature and humidity sensor surpasses a predetermined reference value, the micro control unit controls the heating element to heat the temperature and humidity sensor, evaporating water from the surface of the temperature and humidity sensor. After a period of time, when the humidity value detected by the temperature and humidity sensor is lower than the predetermined reference value, the heating operation is stopped, keeping the temperature and humidity sensor in optimal working condition.
