Star Encyclopedia: Soil moisture transmitter assists intelligent irrigation

Soil moisture transmitter is composed of stainless steel probe and waterproof probe, soil moisture transmitter FDR frequency domain reflection is the use of electromagnetic pulse principle, according to the frequency of electromagnetic wave propagation in the medium to measure the apparent permittivity (ε) of the soil, so as to obtain the soil volume water content (θv). TDR time domain reflection of soil moisture transmitters is a common principle for rapid detection of soil moisture by reflecting waveforms on a mismatched transmission line. The waveform at any point on the transmission line is a superposition of the original waveform and the reflected waveform. FDR has the advantages of simple and safe, fast and accurate, fixed-point continuous, automated, wide range, less calibration, and cheap price. The response time of the TDR principle device is about 10-20 seconds, which is suitable for mobile measurement and fixed-point monitoring. The results are very little affected by salinity, and TDR has all the advantages of FDR, but the equipment is more expensive. Soil moisture transmitters have a wide range of applications in soil and water conservation monitoring, soil hydrology monitoring, precision agricultural production, irrigation and other fields. In large vineyards, in order to obtain better quality grapes, managers actively use transmitter technology, install several soil moisture transmitters, and plan reasonable irrigation strategies through technical accumulation, which not only meet the water required for normal growth of grapes, ensure the best taste of fruit, but also achieve the effect of saving resources. Soil moisture transmitters monitor soil moisture in water-efficient irrigation applications, helping us understand the actual soil moisture status and how much water is needed to grow crops. Soil moisture transmitters are used to obtain reasonable irrigation decisions according to the changes in soil moisture, such as when to irrigate and how much water is needed to irrigate, etc., to avoid the problem of over- or under-irrigation. When the soil moisture transmitter is used, insert the transmitter vertically 90 degrees into the measured soil, do not shake the transmitter when inserting, in order to prevent the soil moisture transmitter probe from being bent and damaging the probe, when removing the soil moisture transmitter, do not directly pull the cable, you need to hold the shell with your hand to pull the soil moisture transmitter out. After the soil moisture transmitter is finished using, use a brush to sweep the dirt on the probe and dry the probe with a soft cloth to protect the probe clean to increase the service life of the soil moisture transmitter.
