This project is aim to improve the temperature and humidity control of clean room, to enhance the control accuracy and reduce fluctuation, to raise the product yield indirectly.
The results showed that the diurnal fluctuation of temperature and humidity had similar tendency between inside and outside of greenhouse under different weather conditions.
