Abstract

The invention provides an FDR-based wireless soil moisture content detection device. The FDR-based wireless soil moisture content detection device comprises a plurality of probes, an outer shell, a circuit board, a battery pack, a capacitor and an antenna assembly, wherein the probe is fixedly connected to the outer shell; the circuit board, the battery pack, the capacitor and the antenna assembly are arranged in the outer shell; the probes are arranged in parallel and are parallel to a first direction; and in the first direction, the circuit board is arranged between the probes and the battery pack. The FDR-based wireless soil moisture content detection device has the beneficial effects that the structure is reasonable and reliable, and the spatial positions of components are reasonably distributed.

Description

technical field [0001] This application relates to a wireless soil moisture detection device based on FDR. Background technique [0002] Soil moisture refers to the moisture content of the soil. Soil moisture is the degree of dryness and wetness of the soil, that is, the actual water content of the soil, which can be expressed by the ratio of soil water to dry soil weight or soil volume, or the percentage of soil water content equivalent to the field water holding capacity, or relative to the saturated water content. Expressed in relative quantities such as percentages. [0003] Existing soil moisture and other parameter detection devices generally use corresponding detection heads with probes or other detection elements to be inserted into the soil for detection. Moreover, the existing FDR-based wireless soil moisture detection devices all need to use wired power supply or wired power transmission to work. This is very unfavorable to the detection environment in the fiel...
