Embodiment

As shown in Figure 1 and Figure 2, a Plants automatic sprinkler of the present utility model, comprise sensor 1, circuits for triggering 2, single chip machine controlling circuit 3 and drive circuit 5, the output signal of described sensor 1 transfers to circuits for triggering 2 through comparator circuit 11, the output signal of described circuits for triggering 2 transfers to single chip machine controlling circuit 3 and drive circuit 5, and the output signal of described single chip machine controlling circuit 3 is sent to selective frequency amplifier circuit 32 through carrier lock circuitry phase 31.

For simplifying circuit, the utility model adopts the dc voltage measurement method without transformer.Sensor 1 adopts humidity sensor or condensation sensor, can put humidity sensor to have in the reality and be permitted in lacunary ceramic cylinder, as the sensor that detects moisture.

Described comparator circuit 11 is made of resistance R 2, adjustable potentiometer RP1, the resistance R 3 of LF356 operational amplifier IC3 and connection thereof, by adjustable potentiometer RP1 setting voltage, compare with the voltage of taking from sensor, imbedding the interelectrode resistance of flowerpot inner sensor is being about 20-50k Ω under the wet state.LF356 operational amplifier IC3 input adds the voltage by resistance R 1 dividing potential drop.In the process of desiccation, voltage rises soil, surpasses at last the voltage that VP1 sets gradually in flowerpot, and the 6th pin output of LF356 operational amplifier IC3 becomes 0V from 5V, because VP1 is adjustable, can make the soil conditions of detection satisfy the growth requirement of plant.

Described circuits for triggering 2 adopt Schmidt trigger IC4, the output of described Schmidt trigger IC4 is connected to CD4049 six phase buffer IC6 through LMC555 timer IC5, the pulse-detecting circuit of Schmidt trigger IC4 produces the trigger impulse that starts LMC555 timer IC5, Schmidt trigger IC4 inside have after the 3V Schmidt trigger circuit, can prevent effectively that error detection from appearring in the output of soil comparator in slow exsiccation process.

Resistance R 5 among the Schmidt trigger IC4 and the time constant of capacitor C 3 determine the width of trigger impulse, and by its triggering timing circuit, trigger impulse appears at the trailing edge (when soil becomes dry by wetting) of Schmidt trigger IC4, and can not occur at rising edge (after the watering, when soil rehumidifies).

The adjustable potentiometer RP2 that is connected by LMC555 timer IC5 output adjusts the watering amount, CD4049 six phase buffer IC6 are received in the output of timer, the electric current suction pump work of base stage is provided for transistor Q2, be used for the limiting motor electric current with the resistance R 8 of series connection of pumps, adjusting rotary speed, because transistor Q2 base bias voltage is electronegative potential, this signal is input to IC1 the 12nd pin I/O end of single-chip microcomputer through resistance R 9 current limlitings, after single-chip microcomputer IC1 internal processor is judged, by LM567 tone decoder IC2 and peripheral capacitor C 10 thereof, the multivibrator component carrier phase lock circuitry 31 that resistance R 11 grades consist of, its frequency of oscillation is by capacitor C 10, the parameter of resistance R 11 determines that carrier frequency is adjusted in the 150-300KHZ scope.
