Integrated Intelligent Management system of Water and Fertilizer based on Internet of things

In order to realize the digital management of vegetable shed, a water and fertilizer integrated intelligent management system based on Internet of things was designed. The sensor collected soil temperature and humidity, air temperature and humidity, lighting conditions and other environmental information, then uploaded the data to cloud server, cloud platform to collate the data, analysis and formulation of vegetable water demand, nitrogen, phosphorus and potassium mixed ratio, Fertilization time and other management plan. According to the experiment, the accumulation of nitrogen, phosphorus and potassium in plant was increased by 7.8812.71% and 4.78%, respectively, based on digital management and fertilization. Compared with the conclusion based on artificial experience control and Internet of things technology, the digitization of Internet of things technology was obtained. The ratio of nitrogen, phosphorus and potassium fertilizer was optimized by management fertilization, and the absorption of nitrogen, phosphorus and potassium nutrients was more adequate in vegetables and fruits.
