The so-called humidity is actually moisture. Because humidity conditions refer to the moisture present in the air and the moisture in the soil. The size of the relative humidity directly affects the photosynthesis of plants, which is strong and requires more water. Therefore, when the temperature is higher and the light is strong, more water is needed to facilitate the formation of photosynthetic products. The increase in soil relative humidity will produce water droplets on the greenhouse, which directly affects the transparency of the greenhouse, and in turn, the illuminance is also affected, so that the humidity will indirectly affect the growth of crops, therefore, it is necessary to adjust the soil moisture of the greenhouse to a reasonable range through the soil moisture transmitter. CSF11 soil moisture transmitter is widely used in soil and water conservation monitoring, soil hydrology monitoring, precision agricultural production, precision irrigation and other fields. Based on the principle of frequency reflection FDR, the CSF11 series soil moisture transmitter is a dielectric sensor that measures the dielectric constant of the inserted medium by measuring the change in capacitance on the sensor at a frequency of 100MHz. 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. The CSF11 soil moisture transmitter circuit reduces the influence of temperature changes on the assay. Digital technology and durable materials enable high measurement accuracy and low price. The CSF11 soil moisture transmitter can continuously monitor the moisture content of multiple plots and different soil depths for a long time.
