Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1: the utility model comprises AC power, power circuit and Humidity Detection control circuit, and power circuit comprises power transformer T, rectifier bridge heap UR, isolating diode VD2, the first filter condenser C1 and the second filter condenser C2; The Humidity Detection control circuit comprises humidity sensor, the first transistor VT1, transistor seconds VT2, the 3rd transistor VT3, first resistor R 1, second resistor R 2, the 3rd resistor R 3, the 4th resistor R 4, the 5th resistor R 5, diode VD1, Zener diode VS and relay K; The negative pole of diode VD1 is connected with the negative pole of isolating diode VD2, first end of relay K, first end of the 4th resistor R 4, the negative pole of Zener diode VS, the colelctor electrode of the first transistor VT1 and first end of first resistor R 1 respectively; The positive pole of diode VD1 is connected with second end of relay K and the colelctor electrode of the 3rd transistor VT3 respectively; The emitter stage of the 3rd transistor VT3 is connected with the emitter stage of transistor seconds VT2 and first end of the 5th resistor R 5 respectively; The base stage of the 3rd transistor VT3 is connected with the colelctor electrode of transistor seconds VT2 and second end of the 4th resistor R 4 respectively; The base stage of transistor seconds VT2 is connected with first end of the 3rd resistor R 3 and the emitter stage of the first transistor VT1 respectively; The base stage of the first transistor VT1 is connected with first electrode of humidity sensor and first end of second resistor R 2 respectively; Second end of first resistor R 1 is connected with second electrode of humidity sensor; Power cathode is connected with second end of second resistor R 2, second end of the 3rd resistor R 3, second end of the 5th resistor R 5 and the positive pole of Zener diode VS respectively, and the normal open switch K-1 of relay is connected in series in the power input of pump motor M.
As shown in Figure 1, the operation principle of the utility model is following:
After the power on circuitry, alternating current 220V voltage produces direct current 6V voltage at the second filter condenser C2 two ends after power transformer T step-down, rectifier bridge heap UR rectification.The dc motor that this voltage one road is supplied with micro pump (adopts the large and medium-sized water pump of ac motor to use the power supply of alternating current 220V power supply; Shown in Fig. 1 dotted line goes out); Another road is after isolating diode VD2 step-down, Zener diode VS voltage stabilizing and the first filter condenser C1 filtering; Produce 5.6V voltage, supply with the first transistor VT1, transistor seconds VT2, the 3rd transistor VT3 and relay K.
The appropriateness sensor is inserted in the soil, and the soil appropriateness is detected.When soil moisture was higher, the resistance value between appropriate sensor two electrodes was less, made the first transistor VT1, transistor seconds VT2 conducting, and the 3rd transistor VT3 ends, not adhesive of relay K, and pump motor M does not work.When soil moisture diminishes; When making resistance value between humidity sensor two electrodes increase to certain value, the first transistor VT and transistor seconds VT2 will end, and make the 3rd transistor VT3 conducting; The relay K adhesive; Its moving together contact is connected, and makes pump motor M energising, and the water spray facility is started working.
Water in soil is increased to a certain degree, and when the resistance value between humidity sensor two electrodes was reduced to certain value, the first transistor VT1 and transistor seconds VT2 conducting again ended the 3rd transistor VT3, and relay K discharges, pump motor M stall.When soil moisture reduces to a certain degree, will repeat the above course of work, thereby make the more constant appropriateness of soil conservation.
Regulate the resistance of second resistor R 2, can change the sensitivity of relay K action.
