The soil moisture transmitter is a transmitter that performs point-of-place monitoring and online measurement of moisture in surface and deep soils. Constructed of stainless steel probe and waterproof probe, it can be buried in soil and dams for a long time. In the fields of soil and water conservation monitoring, soil hydrological monitoring, precision agricultural production, irrigation and other fields, rapid determination of soil moisture in the field is required. The measurement methods of soil moisture transmitter include drying method, ray method, dielectric property method, nuclear magnetic resonance method, separation tracer method and remote sensing method. Among them, the dielectric property method of soil moisture transmitter is to use the dielectric characteristics of soil for indirect measurement, which can realize rapid non-destructive measurement of soil moisture, which can be divided into TDR principle based on time domain reflection and FDR principle based on frequency reflection. Based on the principle of frequency reflection FDR, the soil moisture transmitter is a dielectric type soil moisture transmitter that measures the change in capacitance on the transmitter at a frequency of 100MHz to measure the dielectric constant of the inserted medium. Since water has a very high dielectric constant (80), soil is (3-10). Therefore, when the moisture content in the soil changes, the dielectric constant of the soil also changes considerably. Soil moisture transmitter circuitry reduces the influence of temperature changes on the assay. Soil moisture transmitters use digital technology and durable materials for high measurement accuracy and low price. Soil moisture transmitters enable long-term continuous monitoring of moisture content at multiple plots and at different soil depths. Agriculture is the foundation of the national economy. It is the source of food and clothing for human society, and the foundation of survival. China is a country with a large population, and only by solving the agricultural problem can it have the energy to develop other industries and ensure social stability. Soil moisture transmitters are of great significance to agricultural development.
