Problems solved by technology
However, the electronic soil moisture detection device for plants described in Patent Document 1 requires a battery because it uses an electrical means to measure the moisture content. When the battery is dead, it cannot measure and cannot display
In addition, if the digital display cannot be read, the amount of moisture cannot be known, so it is impossible to simply know the dryness of the soil and whether it needs watering
In addition, although the indicator of Patent Document 2 does not require a battery, it is difficult to adjust the water content (pF value) causing the color change to an appropriate value according to the variety of the plant being grown.

Embodiment Construction
[0055] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in the following description, the same reference numerals are attached to the same components, and descriptions of components that have been described once are appropriately omitted.
[0056] (Construction of moisture indicator for soil)
[0057] Figure 1A as well as Figure 1B It is a figure which exemplifies the moisture indicator for soil. exist Figure 1A The front view of the soil moisture indicator 1 is shown in Figure 1B A side view of the soil moisture indicator 1 is shown in . Fig. 2 is an exploded cross-sectional view illustrating a moisture indicator for soil. As shown in these figures, the soil moisture indicator 1 includes a main body 2 , a front end 3 , a display 4 , an upper end 5 , a water absorbing material 6 , and a color changing portion 7 .
[0058] The main body portion 2 is formed hollow (eg, cylindrical) from a water-impermeable ...

Provided is a soil moisture indicator in which a water-absorbing material and a color-changing part can easily be replaced. The present invention is provided with: a body part that is formed so as tobe hollow by a material through which water does not pass, and that comprises a water-absorbing opening positioned near one end in the longitudinal direction and a transpiration opening positioned near the other end; a display part that is connected to the other end of the body part and allows an inner hollow portion to be viewed; an upper-end part that constitutes the end portion of the display part, that can be removed from and connected to the display part at the end portion on the opposite side to the end portion connected to the body, and that serves as a cap for the hollow portion of thedisplay part; a water-absorbing material that fills the inside of the body part and the display part from at least the water-absorbing opening to the display part; and a color-changing part that is positioned so as to cover the water-absorbing material at the location of the display part, and that changes color tone when in a water-absorbed state and a dry state.
Description
technical field [0001] The present invention relates to a water detection unit, a main body container, and a method of manufacturing a water detection unit for a soil moisture indicator that displays watering timing for maintaining a moisture content of soil suitable for growing plants. Background technique [0002] In order to maintain the moisture content of the soil suitable for plant growth, it is proposed to have an indicator to display the moisture content. For example, a kind of electronic soil moisture detection device for plants (for example, refer to Patent Document 1) and an indicator (for example, refer to Patent Document 2) that detects the humidity of the soil based on the change of the resistance of the soil moisture sensing part are proposed. The container is provided with a porous layer having different transparency between a liquid-absorbing state and a non-liquid-absorbing state so as to be in contact with a water-absorbing material having water-absorbing ...
