Voc detecting and warning method

A VOC (volatile organic compound) detecting and warning method, comprising steps of:

• (a) providing at least one actuating-and-sensing module, wherein the actuating-and-sensing module comprises at least one gas transportation actuator and at least one gas sensor;
• (b) performing a gas-guiding and monitoring operation, wherein the gas transportation actuator is enabled to guide at least one specific amount of gas to the gas sensor, and the gas sensor monitors at least one volatile organic compound of the specific amount of the gas in each monitoring time interval and obtains at least one monitored value corresponding thereto;
• (c) performing a calculating operation, wherein a plurality of the monitoring time intervals are a time unit, and the monitored values are added up during the time unit to obtain at least one metabolism comparison value;
• and
• (d) performing a comparing and warning operation, wherein at least one upper limit of the VOC that a human subject inhales per time unit defines at least one warning threshold value, and the metabolism comparison value is compared with the warning threshold value, wherein if the metabolism comparison value is larger than the warning threshold value, the actuating-and-sensing module issues at least one emergency call, thereby providing at least one protective measure to a user.
