Because of the shortage of water resources, it is common knowledge for everyone to promote water conservation and cherish every drop of water. According to statistics in 1998, China's annual water shortage due to drought will produce about 100 billion kg of grain, and unreasonable agricultural irrigation will waste a lot of water resources. Therefore, water saving irrigation technology has also been developed, and a soil moisture detector has also been developed. To make up for water shortages, how much to fill, and not to waste water resources. The main source of soil moisture is rainfall and irrigation. In a large part of the region north of the Yangtze River in China, it is arid and semi-arid region. The rainfall is seriously insufficient. The output of crops in these regions is severely limited and can only rely on irrigation. Water resources are also severely restricted in these areas. To ensure a certain amount of soil moisture and not to waste water resources, a soil moisture detector is used to monitor the soil moisture changes in real time, and the results of the measurements can be uploaded after testing. To the computer, the use of professional data analysis, such as seeing its analysis, allows us to understand the climax and trough of soil moisture, but also can clearly see the trend of soil moisture changes. However, when using soil moisture to monitor soil drought conditions, there is one thing that cannot be ignored. That is, the change of soil moisture must be combined with the nature of the soil to determine the state of soil drought. Moisture changes are measured.
