Temperature and humidity sensor module heat drying structure

A temperature and humidity sensor module heat drying structure, comprising:

• a first circuit board;
• a second circuit board electrically connected with said first circuit board;
• a temperature and humidity sensor mounted on said first circuit board and adapted for detecting the temperature and humidity of the outside world;
• a heating element mounted on said second circuit board around an outside of said temperature and humidity sensor and adapted for heating said temperature and humidity sensor to evaporate water from the surface of said temperature and humidity sensor;
• and
• a micro control unit mounted on said second circuit board and electrically connected with said temperature and humidity sensor and said heating element, and adapted for controlling the heating operation of said heating element and monitoring the humidity value detected by said temperature and humidity sensor to be lower than a predetermined reference value or not, where said micro control unit controls said heating element to keep heating if the humidity value detected by said temperature and humidity sensor is not lower than said predetermined reference value, or controls said heating element to stop heating if the humidity value detected by said temperature and humidity sensor is lower than said predetermined reference value.
