As a demonstration site for smart agriculture Internet of Things in Pujiang County, Jinhua City, Zhejiang Province, the over 200 acre grape greenhouse of Jin Agriculture Development Co., Ltd. in the county is controlled by computers and combined with the greenhouse's functionsTemperature and humidity sensorThe IoT collector composed of carbon dioxide sensors and other components can not only automatically monitor the temperature and humidity of the greenhouse, but also achieve automatic quantitative supply of water and fertilizer integration, remote diagnosis of pests and diseases, etc. The three-dimensional, multifunctional, and multi-faceted digital management system has shown great potential.

As the brain of the entire park base, in the computer room control room of the greenhouse in the park, the temperature, air humidity, carbon dioxide concentration, and soil moisture data in each greenhouse are updated in real-time on the computer screens on the tables. These large and small data are collected from various greenhouses through temperature, humidity, carbon dioxide sensors, etc. Whether each shed should be ventilated, when it is suitable for watering and fertilizing, and how much should be used can all be determined through these data.

There is a white box hanging in the middle of the grape greenhouse in Block 2 of the park. This box is called an intelligent greenhouse IoT collector, which is equipped with air temperature and humidity sensorsCarbon dioxide sensorVarious information collection devices such as soil moisture sensors. By collecting information through sensors, farmers can obtain greenhouse data at any time, and then automatically water and fertilize with just a click of the mouse based on the computer display, which is very convenient.

According to the farmers in charge of the greenhouse planting, they used to rely on running back and forth between the greenhouses with two legs, observing the numbers on the thermometers and hygrometers hanging inside the greenhouse, and then opening and closing valves one by one. They also had to fertilize each one, and both of them were so busy managing one greenhouse that they couldn't breathe. At present, with this intelligent automation device, it has become easier for one person to manage two greenhouses.

In addition, compared with the traditional way of flood irrigation, which uses large water and wastes water resources, this intelligent irrigation system of water and fertilizer integration, which costs 860000 yuan, can use micro irrigation technology under film to directly use water for crop roots according to different growth periods of crops, which not only guarantees the demand for crop water, but also saves labor and water. Local farmers claim that in the past, watering and fertilizing relied solely on intuition and experience, but now real-time quantification and precise control have been achieved, which not only saves the use of water and fertilizer, but also reduces pests and diseases.
