The operation principle of present embodiment is as follows:
The III detection head is placed under the flowerpot in the water dish, and the II detection head is inserted in the soil of flowerpot middle and upper part, and the I test point is inserted in the soil of flowerpot upper end.Essence has constituted the variable resistance R that resistance reduces with the humidity increase between I, II, the III test point
II-III, R
I-III, R
I-IIDetection head adopts and is difficult for carbonoxide material (as the refuse battery core).When the water tank lack of water is dry, and between I, the II point during (flowerpot top) antecedent soil moisture, potted flower sward earth drying, i.e. R are put in order in expression
II-III, R
I-III, R
I-IIBecome high resistance, the I point is an electronegative potential, and triode V1 base stage is an electronegative potential, V1 ends very high potential of C, and triode V2 base stage is a high potential, the V2 conducting, relay J 1 energising action, the J1-1 contact transfers disconnection to by normally closed, and the J1-2 contact transfers closure to by often opening, relay J 2 energising actions, the J2-1 contact transfers closure state to by often opening, circuit is connected, the pumping motor M (micro pump) that waters work, and water injection system is watered to bonsai flower soil.Water and make at first that ground moistening RI-II reduces between I, II test point, but relay J 1-1 contact is an off-state, and the III test point is still electronegative potential, and watering system continues the work of watering, when linking to each other with detection head III in the water dish at the bottom of infiltrating into flowerpot when watering, resistance R between I, the III test point
I-IIISharply descend, when the III test point changed high potential into, the V1 base stage was a high potential, and V1 conducting C is electronegative potential very, the V2 base stage transfers electronegative potential to, V2 ends, the outage of J1 relay coil, and the J1-1 contact reverts to normally closed, the J1-2 contact often reverts to opens, J2 relay coil outage action. relay J 2-1 contact transfers disconnection to, and the pumping motor M (micro pump) that waters quits work, and watering system stops to water.At interval after certain hour (normally 4-6 days) the water dish elder generation drying, i.e. R
