目前台灣有越來越多建築物因老舊而進行翻新及建造，而在裝潢過程中會使用大量裝潢飾材，例如：木質板材、油漆、黏膠…等，這些飾材中通常就含有甲醛的成份，且會隨時間逐漸逸散至空氣中，但要將裝潢飾材中的甲醛完全逸散殆盡需要很長的一段時間，而長期吸入超標的甲醛，將對人體造成不可逆的傷害，故本研究提出調控裝潢飾材中甲醛逸散量之方法，以減少裝潢飾材中甲醛完全逸散的時間。
經文獻上得知裝潢木飾材之甲醛逸散量與溫溼度有所關聯，故本研究利用溫溼度控制的方式來對裝潢木飾材之甲醛逸散量進行監控，且觀察到溫溼度皆與板材之甲醛逸散量為正相關，然而一般裝潢飾材並不適合處於高濕度環境，因此本研究僅以溫度作為控制變因進行實驗。研究方法為利用感測器偵測甲醛濃度及溫溼度訊號，並經訊號處理及無線傳輸的方式傳至人機介面，當屋內無人時，對室內空氣加溫以增加裝潢飾材中甲醛的逸散量，並適時啟動排風扇將逸散至空氣中的甲醛排出；反之，當有人在屋內時則降低室內溫度以抑制裝潢飾材中的甲醛釋放，將屋內甲醛逸散量盡可能降低。
透過本研究實驗結果得到溫度與板材甲醛逸散量為正相關；相對濕度與板材逸散量亦為正相關，且成功地利用溫度控制木質板材中甲醛逸散量，有效地減少木質板材中甲醛完全逸散殆盡之時間。

At present, more and more buildings in Taiwan are being refurbished and build due to the old age. In the decoration process, a large number of decorative materials are used, such as wood panels, paints, adhesives, etc. which usually contain formaldehyde. And it will gradually dissipate into the air over time, but it usually takes at least six months or even years to completely dissipate the formaldehyde in the decorative materials. Long-term inhalation of formaldehyde will also cause irreversible damage to human body. Therefore, this study proposes a method to regulate the amount of formaldehyde emission in decorative materials to reduce the time for formaldehyde to completely emission in decorative materials.
It is known in the literature that the formaldehyde emission of wood board is related to temperature and humidity. Therefore, this study uses the method of temperature and humidity control to monitor the formaldehyde emission of wood board and observes that the temperature and humidity are positively correlated with the formaldehyde emission of the board, but the general wood board is not suitable for the high humidity environment. Therefore, this study only uses temperature as a control variable to conduct experiments.
The research method is to use a sensor to detect formaldehyde and temperature and humidity signals, and transmit them to the human-machine interface through signal processing and wireless transmission. When there is no one in the house, increase the amount of formaldehyde in the decorative materials by heating the indoor air, and start the exhaust fan to discharge the formaldehyde that escapes into the air at the appropriate time; otherwise, when the person is inside the house, the indoors are lowered. The temperature is used to suppress the release of formaldehyde in the decorative materials, and the concentration of formaldehyde in the house is reduced as much as possible.
Through the experimental results of this study, the temperature is positively correlated with the formaldehyde emission of the board; the relative humidity is positively correlated with the plate dissipation, and the temperature is used to control the formaldehyde emission in the wood board, effectively reduce the time it takes for the wood board to completely emission.
