The soil temperature sensor consists of a power module, a temperature sensor module, a transmitter module, a temperature compensation module and a data processing module, which completely solves the measurement error introduced by the platinum resistor due to its own characteristics. The sensor has a zero drift circuit and a temperature compensation circuit, which has a high adaptability to the use environment. The soil moisture part is a high-precision and high-sensitivity sensor for measuring soil moisture based on the frequency domain reflection principle and manufactured using high-frequency electronic technology. By measuring the dielectric constant of the soil, it can directly and stably reflect the true moisture content of various soils, and can measure the volume percentage of soil moisture. It is currently the most popular soil moisture measurement method in the world.
The soil conductivity sensor uses a stainless steel probe to convert the soil conductivity through the sensor into an analog or digital signal. During the development process, it absorbs the advanced technology of similar foreign instruments, and combines the actual situation and use requirements of my country to convert the conductivity value into a corresponding analog or digital signal. After burying this conductivity sensor in the soil, the conductivity of the soluble salt ions in the soil solution is directly measured. Stainless steel electrodes have the characteristics of stable performance and high sensitivity, and are suitable for a wide measurement range, especially for high conductivity, so they are very suitable for the determination of soil conductivity.
