Problems solved by technology

For example, if ten fixed-point monitoring points are set up in the field, in order to obtain daily data, it is necessary to send people to the field to measure manually every day, and it is even more difficult to obtain data at shorter intervals
Manual operation, mainly the factor of manually lifting the moisture sensor probe up and down greatly limits the application of this type of sensor

Description

technical field [0001] The invention belongs to the fields of soil moisture measurement and automatic monitoring quantity, and in particular relates to a sensor control device and a soil moisture monitoring device including the device. Background technique [0002] The monitoring of soil moisture storage and its changing law is one of the basic tasks in the monitoring of agricultural meteorology, ecological environment and hydrological environment. Mastering the law of soil moisture changes is of great significance to agricultural production, moisture monitoring and forecasting, and other related ecological environment monitoring and forecasting services and theories. [0003] The tube moisture sensor is a special instrument used to measure the moisture content of different depth profiles of soil. At the fixed-point monitoring point, first bury PVC plastic pipes of appropriate size as required, and try to ensure that the outer pipe wall is in close contact with the soil wit...
