The detecting unit 2 is composed of two pairs of an electric conductor pair 2a and an electric conductor pair 2b, and has a structure in which 2a and 2b are inserted into the soil at a distance, and between the 2a and 2b. The identification unit 7 has a function of outputting a signal that enables the identification unit 7 to identify whether or not the current is generated by using water as a medium. For this reason, excellent electrical conductivity is required, and since the material must be excellent in corrosion resistance to be used by being inserted into the soil, stainless steel is used here. The material of the detection unit 2 is not limited to stainless steel, and may be other metal materials or functional plastics as long as it is a material excellent in electric conductivity and corrosion resistance, and is not particularly limited.
[0008]
The control unit 3 is the center of the soil moisture detection and notification device 1, and a circuit necessary for managing the soil moisture detection and notification device 1 is incorporated therein. The identification unit 7 always receives information sensed by the identification unit 7 about the electrical conduction state occurring in the water medium between the remote electrical pair between the electrical pair 2b and the identification display / light emitting unit 4a of the display unit 4 according to the state. The information control / emission display unit 4b, the external control unit 6, and the electronic switch unit 8 have a function of transmitting necessary information.
Although 4b is newly set as a controllable display with enhanced display power, 4a can be used for general display.
[0009]
The display unit 4 includes an identification display / light emitting unit 4a and a notification control / light emitting display unit 4b. The display unit 4 has a function of displaying and notifying the moisture state in the soil by light emission, non-light emission, sound, or the like according to an instruction from the control unit 3. Have
In the moisture detection and notification device 1 for soil, the control unit 3 is designed so that the control unit 3 is hidden in the presence of water in the soil and blinks a red lamp in the absence of water in the soil. .
The display on the display unit 4 is made non-light-emitting and light-emitting (character light-emitting) due to the electric current flowing through the medium and the current being de-energized while the electric good pair 2a and the electric good pair 2b of the detecting unit 2 are separated. ), Light emission and light emission (including character light emission), and it is also possible to use pictures and characters together with these, or to use sounds together.
Alternatively, only the notification by voice may be performed, but the selection of these methods can be left to the circuit design of the control unit 3.
[0010]
The power supply unit 5 is a power source of the moisture detection and notification device 1 in the soil.
Although the power supply unit 5 uses two AAA batteries here, it is not limited to AAA batteries and may be a solar battery or the like.
[0011]
When the external control unit 6 is used on a submerged pump unit and a water sprinkling unit or on a line in water circulation, the external control unit 6 controls a water replenishing unit 6a including a valve opening / closing unit and a water sprinkling unit to supply water. Things.
[0012]
The identification unit 7 is for distinguishing between an energized state and a non-energized state using water generated as a medium between the electrically conductive pairs 2a and 2b of the water detection unit 2 as a medium.
[0013]
The electronic switch unit 8 is for minimizing power consumption, and is for preventing electricity other than indispensable to be supplied to the notification control / light emitting display unit 4b which consumes relatively large power.
[0014]
The case cover 9 protects the inside of the main body, and facilitates battery holding and battery replacement of the power supply unit 5.
[0015]
The main body case 10 is used to enclose the entire product in a good shape, maintain the safety and appearance of the product, and enhance the commercial value.
