8.系统管理包括设备管理、用户管理、区域管理、系统日志四部分。 Agricultural four monitoring instruments and equipment, as the name suggests, include four important monitoring functions: soil moisture, seedling condition, insect condition, and disaster condition. These four monitoring functions are interrelated and together constitute a comprehensive monitoring system for agricultural production. Through this device, farmers can obtain real-time information on soil moisture, plant growth status, pest and disease conditions, as well as natural disaster warnings, thereby more scientifically managing agricultural production. Through soil moisture sensors, the device can monitor the soil moisture status in real time, providing accurate irrigation and drainage decision-making basis for farmers. In this way, not only does it improve the efficiency of water resource utilization, but it also helps to prevent crop damage caused by excessive irrigation or poor drainage.
