Soil Moisture Sensor Also known as Soil Moisture Sensor, it consists of a stainless steel probe and a waterproof probe, which can be buried in the soil and embankment for a long time. Soil moisture sensors are mainly used to measure the relative soil moisture content and temperature for soil moisture monitoring, agricultural irrigation and forestry protection. Soil moisture sensor adopts frequency domain or time domain principle, the mainstream soil moisture sensor on the market adopts FDR frequency domain reflection principle, FDR (Frequency Domain Reflectometry) frequency domain reflectometer is a kind of instrument used to measure soil moisture, it uses the electromagnetic pulse principle, according to the frequency of electromagnetic wave propagation in the medium to measure the soil apparent dielectric constant, so as to get the soil moisture content and temperature, so as to get the soil moisture content. It utilizes the electromagnetic pulse principle to measure the apparent dielectric constant of the soil based on the frequency of electromagnetic wave propagation in the medium to obtain the relative moisture content of the soil. The FDR in soil moisture sensor has the advantages of simplicity and safety, rapidity and accuracy, continuous fixing point, automation, wide range and less calibration. It is a recommended instrument for soil moisture determination. Soil Moisture Sensor CSF11 product features: a) Soil Moisture Sensor CSF11 is capable of measuring volumetric soil moisture content and temperature in a volume range of 200cm around the probe. b) The Soil Moisture Sensor CSF11 utilizes a 100MHz circuit design. c) The Soil Moisture Sensor CSF11 has a low sensitivity in highly saline and clayey soils. d) The Soil Moisture Sensor CSF11 is IP68 rated and can be buried in the soil for long periods of time. e) Soil moisture sensor CSF11 with wide voltage supply, non-linear correction, high accuracy and consistency. f) The Soil Moisture Sensor CSF11 is small, lightweight and easy to install. g) The Soil Moisture Sensor CSF11 is designed to be resistant to lightning strikes and frequency cut-off interference, and has a strong anti-interference capability. h) Soil moisture sensor CSF11 has reverse wiring and over-voltage protection, current limit protection (current output). Soil moisture sensor is widely used in water-saving agricultural irrigation, greenhouse, flowers and vegetables, grass pasture, soil quick test, plant culture, scientific experiments and other fields.
