秋季温室番茄环境因子变化规律研究-基于无线传感网络
Research on Regular Pattern of Autumn Environmental Factors in Greenhouse Tomato Based on WSN
摘要
Abstract
The key factors that restrict the yield and quality of vegetables are the environmental factors.In order to ex-plore the change regulation of environmental factors in greenhouse, we used Wireless Sensor Network ( WSN) to get the data of environmental factors at different height and location in different time.The results of analysis show that the range of temperature and humility were different, light intensity reduced, illumination time shorter and changes in carbon diox-ide concentrations delayed.During the day, the canopy temperature, light intensity is higher than others, the humility is lower than other heights and the intermediate layer close to the root layer, while the three layers were close during the night.Temperature from south to north and humility from north to south were high to low, the maximum difference of light intensity and CO2 concentration are 6562.5lux , 93.76ppm,respectively.Test results show that the WSN can pro-vide reference and decision support for greenhouse environmental control.关键词
