Shandong Lianyun Agricultural Meteorological Station Information Monitoring System
As a data collection tentacle, the soil sensor immerses directly into the soil, measures the soil water content and related parameters in real time, according to the measurement principle can be divided into two types: capacitor (main type), time domain reflex (TDR), the main parameters and characteristics are as follows:
Volumetric water content in soil (VWC, basic parameters):measurement range 0 - 100%, accuracy ±2% (within 0 - 50% measurement), resolution 0.1%, can directly reflect the actual soil water content;
Soil temperature:Some sensors have integral temperature measurement functions, range - 40 ~ 85°C, accuracy ±0.5°C, auxiliary analysis of moisture movement (for example, slow conductivity of soil moisture at low temperatures, need to adjust the frequency of irrigation);
Soil electrical conductivity (EC, optional):measurement of salt content in soil, range 0 - 20mS/cm, avoiding impact on crop absorption due to excessive salinity, guide irrigation salt rinsing.
Probe material:Using 316L stainless steel or epoxy resin coating, corrosion resistance, aging resistance, adapt to acidity, alkalinity and other various soil environments, service life up to 3 - 5 years;
Number of probes:2 - 4 probes (usually 3 pieces), inserted into a soil depth of 5 - 20 cm (adjustable), ensuring close contact with the soil and reducing measurement errors;
Protection class:IP68 waterproof design, which can be buried underground for a long time, withstand rainwater immersion, soil extrusion, suitable for long-term outdoor monitoring.
Covers the needs of various types of agricultural crops, water-saving irrigation works (drip irrigation, irrigation, micro-irrigation systems), agricultural facilities (greenhouses of vegetables, flowers), orchards and commercial forests (apples, citrus fruits, tea plantations), large-scale field plantings (wheat, corn, rice)
