Temperature, air humidity, light Zhao intensity and carbon dioxide concentration control factor is the main parameters of greenhouse cultivation environment, vegetable growth speed, quality, and these parameters have close relationship, and effectively control the factor can improve the yield and quality of vegetables, achieve the goal of saving time and increase production. The system to STC89C52 microcontroller as the main control chip, the wireless communication...
