Abstract
A kind of flowerpot soil water deficient reminding function device, including flowerpot, the electric resistance of soil resistance R of 2 points of A, B in flowerpotSoilWheatstone bridge is connected into variable resistance R2, resistance R4, resistance R3, B, D of Wheatstone bridge are connected with power supply U, it is connected in parallel between A, C point of Wheatstone bridge after green LED lamp VD1, resistance R5 series connection, it is connected in parallel between A, C point of Wheatstone bridge after red LED lamp VD2, resistance R6 series connection, green LED lamp VD1, red LED lamp VD2 are mounted on outside flowerpot；Using the difference of soil resistivity under different water cut, soil moisture content is higher, and resistivity is smaller, otherwise bigger；When aqueous sufficient in flowerpot, green LED lamp VD1 is always on, and in flowerpot water shortage, green LED lamp VD1 extinguishes, and red LED lamp VD2 is bright.The utility model can be in flowerpot soil water shortage, to people to remind.
Description
Technical field
The utility model is related to a kind of alarm sets, and in particular to a kind of flowerpot soil water deficient reminding function device.
Background technology
For daily people during floriculture at home, water shortage is serious for soil in flowerpot frequent occurrence, but people fail and
Shi Faxian lacks necessary soil water deficient reminding function instruction device, leads to plant undergrowth or withered to fail to water in time
And it is dead.
Invention content
In order to overcome the disadvantages of the above prior art, the purpose of this utility model is to provide a kind of flowerpot soil water shortages to carry
Awake device, can be in flowerpot soil water shortage, to people to remind.
In order to achieve the above object, the technical solution that the utility model is taken is：
A kind of flowerpot soil water deficient reminding function device, including flowerpot 1, the electric resistance of soil resistance R of 2 points of A, B in flowerpot 1SoilWith can
Becoming resistance R2, resistance R4, resistance R3 and connects into Wheatstone bridge, B, D of Wheatstone bridge are connected with power supply U, green LED lamp VD1,
It is connected in parallel between A, C point of Wheatstone bridge after resistance R5 series connection, favour stone is connected in parallel on after red LED lamp VD2, resistance R6 series connection
Between A, C point of electric bridge, green LED lamp VD1, red led lamps VD2 are mounted on 1 outside of flowerpot.
The variable resistance R2 models RM-065 201, adjustable Standard resistance range is 0~200 ohm, resistance R4 is 50
Ohm, resistance R3 are 50 ohm, resistance R5 is 100 ohm, resistance R6 is 100 ohm.
The green LED lamp VD1 specifications are 5mm, 1~3.5V of operating voltage；Red LED lamp VD2 specifications are 5mm, work electricity
Press 1~3.5V.
The beneficial effects of the utility model are：Utilize the difference of soil resistivity under different water cut, soil moisture content
Higher, resistivity is smaller, otherwise bigger；When aqueous sufficient in flowerpot, green LED lamp VD1 is always on, in flowerpot water shortage, green led
Lamp VD1 extinguishes, and red LED lamp VD2 is bright.The utility model can be in flowerpot soil water shortage, to people to remind.
Description of the drawings
Fig. 1 is the schematic diagram of 2 points of A, B in the utility model flowerpot.
Fig. 2 is the circuit diagram of the utility model.
Specific implementation mode
The utility model is described in detail below in conjunction with the accompanying drawings.
Referring to Figures 1 and 2, a kind of flowerpot soil water deficient reminding function device, including flowerpot 1, the soil of 2 points of A, B in flowerpot 1
Resistance RSoilWheatstone bridge is connected into variable resistance R2, resistance R4, resistance R3, B, D and power supply U of Wheatstone bridge connect
It connects, is connected between A, C point of Wheatstone bridge after green led lamps VD1, resistance R5 series connection, red led lamps VD2, resistance R6 series connection
It is connected to afterwards between A, C point of Wheatstone bridge, green led lamps VD1, red LED lamp VD2 are mounted on 1 outside of flowerpot.
The variable resistance R2 models RM-065 201, adjustable Standard resistance range is 0~200 ohm, resistance R4 is 50
Ohm, resistance R3 are 50 ohm, resistance R5 is 100 ohm, resistance R6 is 100 ohm.
The green LED lamp VD1 specifications are 5mm, 1~3.5V of operating voltage；Red LED lamp VD2 specifications are 5mm, work electricity
Press 1~3.5V.
The operation principle of the utility model is：
Utilize resistance value R under soil different moisture contentSoilVariation, so that A, C point voltage in Wheatstone bridge is changed,
Green LED lamp VD1, red LED lamp VD2 is caused to extinguish or be connected under the conditions of different voltages, to indicate water content in flowerpot
Variation, to remind people to water in time.
When first used, when flowerpot soil is in the critical point to be watered, two probe electrodes is inserted into flowerpot and are worked as
In, electrode cable is being accessed by A, B point in figure in circuit, R in circuitSoilIndicate electric resistance of soil in flowerpot, it is variable by adjusting
Resistance R2 makes green LED lamp VD1, red LED lamp VD2 go out, and at this time A, C point voltage are 0, Wheatstone bridge balance.
If soil dehydration, electric resistance of soil RSoilIt will increase, Wheatstone bridge balance is broken, and C point voltages are higher than A points, this
When red LED lamp VD2 conducting, glow, remind water shortage, after watering, electric resistance of soil RSoilReduce, A point voltages are higher than C points, red led
Lamp VD2 will extinguish, and green LED lamp VD1 conductings will send out green light, prompt soil water amount sufficient.
Resistance R5 and R6 is current-limiting resistance.
