The agricultural automatical water feeder circuit is composed of the power supply circuit, multivibrator, monostable trigger, relay K, AC contactor KM and water detection electrodes (a ~ c) and other components, and the circuit is shown as the chart 1. Power supply circuit is composed of the power transformer T, rectifier diodes VD1 ~ VD4, three-terminal integrated voltage regulator IC1 and filter capacitor C1. Multivibrator is composed of the time-base integrated circuit IC2, resistors R1, R2 and capacitor C2 and so on. The monostable trigger is composed of the time-base integrated circuit IC3, resistors R3, R4, and capacitor C3 and other components. R1 ~ R4 select 1/4W carbon film resistors.
