The agricultural automatical water feeder circuit is composed of the power supply circuit and water level detection control circuit, and the circuit is shown as the chart 1. Power supply circuit is composed of the power transformer T, bridge rectifier UR and filter capacitors C1, C2. Water level detection control circuit is composed of the water level detection electrodes A ~ C, four NAND gates integrated circuit IC (D1 ~ D4), transistor V, resistors R1 ~ R3, relay K and diode VD. AC 220V voltage is bucked by T , rectified by UR and filtered by C1, C2 to provide 12V voltage for relay K and IC. R1 ~ R3 use the carbon film 1/4W resistors or metal film resistors.
