The soil monitoring system can realize long-term continuous monitoring of soil parameters. Users can flexibly arrange soil sensors according to monitoring needs; they can also arrange sensors at different depths to measure soil moisture in the profile. The system also provides additional expansion capabilities. Corresponding sensors can be added according to monitoring requirements to monitor soil temperature, soil conductivity, soil pH, air temperature, air humidity, light intensity, wind speed, direction, rainfall, and other information , So as to meet the needs of system function upgrade. The soil moisture monitoring system can comprehensively, scientifically and truly reflect the soil changes in the monitored area, can provide timely and accurate soil moisture status at each monitoring point, and provide important basic information for disaster reduction, drought resistance, fertilization and irrigation.
