Embodiment Construction

[0029] see figure 1 A. figure 1 B, the setting method of using the embedded soil water content sensor in this embodiment is specifically carried out according to the following procedures:

[0030] a. On the ground 1 of the soil water content test point, remove the debris on the surface, and draw the excavation range of the test pit 2;

[0031] b. Use a shovel to excavate the soil layer by layer according to every 10cm thick horizontal layer, and put the raw soil of different horizontal layers into plastic bags respectively, and dig to the design depth;

[0032] c. Place the sensor 4 vertically in the center of the test pit 2, the top surface of the sensor 4 is flush with the ground 1, backfill symmetrically in layers on both sides of the sensor 4 and compact the original soil to the ground 1;

[0033] d. On the ground 1 where the sensor 4 is located, pave a circular gravel layer 3 with a thickness of 2 to 3 cm and a diameter of 100 cm, dig out drainage ditches around the gra...

Abstract

The invention discloses an embedded soil moisture content sensor and application thereof. The sensor is characterized in that the cylindrical sensor is formed by inserting in series and assembling a plurality of unit test cylinders along the axle direction of the cylinder, wherein the upper end of the cylinder is provided with a top cover, while the lower end is provided with a base; and a screw penetrates the center of the cylinder for connecting and fixing. A soil moisture content tester and a solar cell panel matched with the soil moisture content sensor and the soil moisture content sensor can automatically and regularly send testing data of soil moisture content with different depths from the earth surface wirelessly. The soil moisture content sensor has the characteristics of high accuracy, good resolution, high response speed, low cost, small floor area, real-time long-distance data acquisition and the like, and is advanced instrument equipment for a soil moisture content information acquisition system.

Description

technical field [0001] The invention relates to a sensor for testing soil water content in a soil moisture information collection system and a setting method thereof, in particular to an embedded soil water content sensor and a setting method. Background technique [0002] At present, in the instruments and equipment of the soil moisture information collection system, the drying method, tensiometer method, neutron moisture meter method, time domain reflection method or frequency domain method are used to test the soil moisture content, which has the disadvantages of low automation and testing Different problems such as shallow depth, large interference from human factors, and high environmental requirements have brought inconvenience to the collection of soil moisture information. Contents of the invention [0003] The purpose of the present invention is to provide an embedded soil water content sensor and its application, so as to flexibly measure soil water content data ...
