The invention relates to a novel time domain reflection type soil measuring device and method. The device comprises a signal control and processing system, a power supply module and a probe, wherein the signal control and processing system comprises a Wi-Fi chipset, a circulator and a microcontroller, the Wi-Fi chipset comprises a first Wi-Fi chip and a second Wi-Fi chip, and the first Wi-Fi chip and the second Wi-Fi chip are respectively connected with the microcontroller and are also respectively connected with the probe through the circulator. According to the scheme provided by the invention, on the basis of a traditional TDR technology and different from traditional TDR equipment, two Wi-Fi chips are innovatively adopted as a signal emission source and a signal receiver of high-frequency signals respectively, and the soil moisture content and conductivity can be measured at the same time by measuring related parameters of propagation of the signals in a soil medium; the measurement accuracy is improved; and the cost and the implementation difficulty are greatly reduced.
Description
technical field [0001] The invention belongs to the field of soil measurement, and in particular relates to an innovative time-domain reflective soil moisture and conductivity measurement device and method based on a Wi-Fi chip set. Background technique [0002] Soil moisture, as the main supply source of water required for crop growth, plays an important role in crop growth. Too little water in the soil will cause the soil to harden, which is not conducive to the absorption of water and nutrients by the crops, and affects the growth of the crops. Excessive soil moisture will affect the vitality of crop roots, which is also not conducive to crop growth, and may cause fertilizer loss and pollution. Crops absorb nutrients such as inorganic salts from the soil while absorbing water. The electrical conductivity of soil can reflect the actual situation of soil salinity under a certain water condition, which affects the transformation of soil nutrients, the effectiveness of the ...
