The agricultural automatical water feeder circuit is composed of the power supply circuit, water level detection circuit and control implementation circuit, and the circuit is shown as the chart 1. Power supply circuit is composed of the power transformer T, rectifier diodes VD1 ~ VD4 and filter capacitor C. Water level detection circuit is composed of the high water level electrode A, low water level electrode B and the main electrode C. Control implementation circuit is composed of the relay K, control transistor V and AC contactor KM and other components. AC 220Y voltage is bucked by T, rectified by VD1 ~ VD4 and filtered by C to produce the DC 12V voltage for control implementation circuit.
