Temperature and humidity sensor module sensing method

A temperature and humidity sensor module sensing method, comprising the steps of:

• (a) using a micro control unit to read and record a humidity value detected by a temperature and humidity sensor for a predetermined period of time;
• (b) said micro control unit determining whether the rising slope of said humidity value in said specific period of time exceeds a predetermined rising slope and said humidity value continues to be higher than a predetermined high humidity limit, and then performing step (c) if “Yes”, or step (l) if “No”;
• (c) said micro control unit recording a humidity lower limit value;
• (d) said temperature and humidity sensor detecting a temperature value and determining whether said temperature value is lower than a high temperature limit, and then performing step (f) if “Yes”, or performing step (e) if “No”;
• (e) turning off said heating element and then continuously performing step (d);
• (f) turning on said heating element;
• (g) said micro control unit determining whether the falling slope of said humidity value in said specific period of time exceeds a predetermined falling slope and said humidity value continues to be lower than said predetermined high humidity limit, and then performing step (h) if “Yes”, or performing step (i) if “No”;
• (h) turning off said heating element and then continuously performing step (j);
• (i) using said micro control unit to read the said humidity value detected by said temperature and humidity sensor and then continuously performing step (d);
• (j) determining whether the said humidity value detected by said temperature and humidity sensor reaches the said humidity lower limit value, and then performing step (i) if “Yes”, or performing step (k) if “No”;
• (k) using said micro control unit to read the said humidity value detected by said temperature and humidity sensor, and then continuously performing step (j);
• and
• (l) said micro control unit transmitting said humidity value to an upper control system, and then continuously performing step (a).
