Most commercially available growth chambers can only control a few factors of the environment and have the inflexible human-machine interface. Even so, they are still expensive and have no data acquisition capability. The purpose of this research is to develop a computerized control and data acquisition system of a growth chamber. The system is developed using MS Visual Basic and capable of controlling temperature, humidity, light, and concentration of CO2. Besides the single-point setting, two-step setting, daily multi-step setting and long-duration-muti-step setting, the human-machine interface of the system also provides the acclimatization-curve setting. Users can setup the acclimatization curves in form of sine-wave or triangle-wave and adjust the amplitude of the curve easily. The system developed can greatly improve the performance of the commercially available growth chamber. Thus, making it highly marketable. More test runs are required to insure the stability of the system.
