Continued technological advances and growing market demand have driven the iterative updating of soil moisture monitoring technologies. The drying method, which was initially used to assess soil moisture by weighing, has since evolved to the electrical resistance method, which is based on the relationship between soil electrical conductivity and moisture content. The frequency domain method further utilizes the propagation characteristics of electromagnetic waves in different media to determine moisture. The dielectric constant method relies on the direct correlation between soil dielectric constant and moisture content. The time-domain method (TDR) assesses moisture content by measuring the propagation time and attenuation of electromagnetic waves in the soil. The evolution from a single technology to an integrated monitoring solution has greatly improved the accuracy and ease of operation of soil moisture monitoring.

The time-domain method moisture monitoring technology has demonstrated the ability to provide real-time monitoring, high accuracy, and long-term continuous monitoring in practical applications. It is also easy to operate, does not require calibration, is safe for human beings and the environment, and is suitable for a wide range of soil types, making it an ideal choice for soil moisture monitoring.

This type of soil moisture monitoring system consists of an intelligent monitoring terminal, a soil moisture sensor and a solar-powered panel, which has low sensitivity to soil salinity and can be deployed underground in a durable manner, making it suitable for a variety of soil environments. The system is capable of continuously monitoring temperature and moisture changes in the soil from three to five layers in depth to quickly obtain a comprehensive view of soil conditions. It is so capable of providing soil moisture data in real time, which provides important data support for flood and drought prevention and other disaster control work.
