Abstract

The present invention relates to a device for measuring the water content of a soil using a current value that varies depending on the soil water content, and a method for measuring the water content of the soil. The non-powered soil moisture content measuring apparatus of the present invention can be widely used for horticulture, agriculture, soil geological survey, and the like because it is cheap and convenient to carry.

Description

Technical Field [0001] The present invention relates to an apparatus for measuring water content of a non-power source using a galvanic cell and a method for measuring water content of the soil,

The present invention relates to a device for measuring the moisture content of a non-electric power source and a method for measuring the water content of soil, and more particularly, to a device for measuring moisture content of a soil using a current value depending on the soil water content, .

As the water content in the ground increases, the collapse of the soil occurs due to the mechanism that reduces the sole angle of the soil and reduces the shear strength of the ground. Soil disintegration causes a lot of economic and human losses, and a system is required to predict moisture content in the ground to minimize the loss. In addition, as the amateur gardening households in horticulture in the home are increasing, it is required to develop an inexpensive soil moisture content measuring device which can measure moisture content of the potted soil in real time.

Existing Soil Moisture Analyzers are able to know the water content of the soil in which the general soil or plant grows by comparing the data obtained by checking the water evaporation with the electric sensor using direct heating or infrared rays to the standard (water tension) Is bulky, difficult to use, takes a long time to measure, and is expensive and is operated only in some laboratories. In addition, small-scale soil water content measuring devices are inevitably used due to various problems such as high cost or damage to the root of the plant while the probe is deeply embedded in the soil.

Korean Patent Laid-Open No. 10-2011-0017617 (Feb. 22, 2011) relates to a device for measuring high-frequency soil moisture, and a device for measuring moisture using high frequency is disclosed. The moisture of soil and grain is measured using high frequency A reference antenna unit having a shape of 'cylinder' or 'rod', a transmission antenna unit radiating a high frequency wave to the soil on the outer wall of the reference antenna unit, and a high frequency wave radiating to the soil from the transmission antenna unit And measuring a change in the received signal according to the dielectric constant and the capacitance using the measuring antenna unit having the receiving antenna unit for receiving the signal.

The present invention relates to a method and apparatus for measuring moisture content in a soil moisture content measuring apparatus, in which a soil moisture content measuring apparatus can be used more easily, and the cost is low, the operation is convenient, the measuring time does not take long, And to provide a method of measuring the moisture content of the apparatus and the soil which is easy to maintain and economical because it is not necessary.

The measurement of moisture content of the non-power source soil according to the present invention is based on the principle of a galvanic cell. As the water content of the soil increases, the internal resistance decreases and the amount of current increases. The apparatus of the present invention measures the water content of soil from the measured current value using a small probe of 1.0 cm x 1.5 cm, a resistance of 1 k ohm and an ammeter.

Since the measurement apparatus itself is a galvanic cell, it is not necessary to supply power separately and a very small probe (1.0 cm x 1.5 cm) is used, so that it is easy to store and the horticultural crop is damaged There is no need to worry about it. In addition, since the moisture content corresponding to the current value is indicated in the ammeter of the non-power source soil moisture content measuring apparatus of the present invention, the water content of the soil can be confirmed immediately after the probe is inserted into the soil.

The present invention has revealed a water content corresponding to a measured current through an experiment for measuring a current value depending on a water content. Experimental results show that the output of the current changes from 0 to 40% of the water content.

. By using this formula, the moisture content (%) corresponding to the current value indicated on the ammeter is indicated, and the probe and resistor are connected in series to produce a ready-to-use soil moisture meter.

The non-powered soil moisture content measuring apparatus of the present invention can be widely used for horticulture, agriculture, soil geological survey, and the like because it is cheap and convenient to carry.
