FIELD OF THE INVENTION

The present disclosure relates to a VOC detecting and warning method, and more particularly, an actuating-and-sensing module is utilized in the VOC detecting and warning method. The actuating-and-sensing module sucks gas therein and monitors volatile organic compounds of the gas.

BACKGROUND OF THE INVENTION

Recently, the air pollution problem becomes more and more serious. Consequently, people pay much attention to the methods of avoiding the harmfulness of various pollutants in the air. As known, volatile organic compounds (VOCs) are the common pollutants that are present in the air. The VOCs are in a gaseous form at room temperature and have strong volatility. For example, the VOCs include formaldehyde, toluene, xylene, ethylbenzene, propylene benzene, and so on. In addition to the exhaust gases from fuel combustion and vehicle transportation, the sources of the VOCs are diverse. For example, the VOCs are often dispersed in indoor environments through construction and decorative materials such as paints, coatings and adhesives. The VOCs may cause damage to the human bodies over the years. If the concentration of the VOCs in a room exceeds a specific concentration, people feel headache, nausea, vomit and limb weakness in a short time. In severe cases, people may have convulsions, coma and memory loss. Moreover, the VOCs harm people's livers, kidneys, brains and nervous systems, and they also contain many carcinogens.

However, the current technologies of detecting the VOCs still have some drawbacks. For example, in case that the volume of the detection device is small, the detection device is usually unable to immediately and accurately detect the VOCs. In addition, there is no detection device on the present market that can be carried and warn the user in real time when the amount of the VOCs in the environment reaching a hazard level is detected.

Therefore, there is a need of an improved VOC detecting and warning method in order to overcome the drawbacks of the conventional technologies that the accuracy of detecting the VOCs is low and fails to warn the user in real time.

SUMMARY OF THE INVENTION

An object of the present disclosure provides a VOC detecting and warning method, which utilizes a gas transportation actuator of an actuating-and-sensing module to guide the gas to a gas sensor of the actuating-and-sensing module. Then, the gas sensor detects the VOCs of the gas and generates a monitored value according to a result of detection in each monitoring time interval. All the monitored values obtained in a unit time period are accumulated and calculated to obtain an average comparison value. Then, the average comparison value is compared with an injury threshold that is defined according to the VOC inhalation amount affecting the health of a human body. If the average comparison value is greater than the injury threshold, the actuating-and-sensing module issues a warning notification to warn the user. Since the gas is guided to the gas sensor, the accuracy of the VOC detection is increased. In addition, once it is determined that the amount of VOCs in the environment has reached a hazard level, the user is warned in real time. Therefore, the drawbacks of the conventional technologies that the accuracy of detecting the VOCs is low and fails to warn the user in real time can be addressed.

In accordance with an aspect of the present disclosure, a VOC detecting and warning method is provided. Firstly, an actuating-and-sensing module having a gas transportation actuator and a gas sensor is provided. Then, the gas transportation actuator guides a specified amount of gas to the gas sensor, and the gas sensor generates a monitored value according to a result of detecting volatile organic compounds of the gas in each monitoring time interval. All the monitored values obtained in a unit time period are accumulated and calculated, so that an average comparison value is obtained. If the average comparison value is determined greater than an injury threshold, which is defined according to the VOC inhalation amount affecting the health of a human body, the actuating-and-sensing module issues a warning notification to notify the user to take protective measures.

In an embodiment, the actuating-and-sensing module further includes a microprocessor and a transmission module. The microprocessor processes the monitored values to generate output data and controls the gas transportation actuator to actuate. The transmission module transmits the output data to a connection device, so that information carried by the output data is displayed, stored and transmitted by the connection device.

The above contents of the present disclosure will become more readily apparent to those ordinarily skilled in the art after reviewing the following detailed description and accompanying drawings, in which:
