Abstract: This Photosynthesis acts as a major role in determining the carbon dioxide and oxygen content of the present atmosphere, and it is often convenient to equate the rate of carbon dioxide assimilation with photosynthesis. We hope that the photosynthesis can be initiated to reinforce the balance of concentration of carbon dioxide and oxygen in our room. However, we have to find out the plants with higher efficiency of carbon dioxide assimilation. Therefore, We designed a computer-based automatic measurement system used to estimate the efficiency of carbon dioxide assimilation on photosynthesis. The plants in good condition were placed in an airtight and non-transparent box. After that, the box was filled with a constant concentration of carbon dioxide and then the fluorescent lamps were turned on to give rise to the photosynthesis of the plants. At the same time, the decreasing concentration of carbon dioxide in the box due to the progress of photosynthesis was measured and recorded by the system for a constant period of time. From the experimental results, the efficiency of carbon dioxide assimilation of the plants can be characterized as the rising time, falling time, peak value, average value, and the slope of these concentration curves.
