The agricultural automatical water feeder circuit is composed of the electrode A, electrode B, time-base integrated circuit IC, control transistor V, power transformer T, rectifier diodes VD1 ~ VD4 and relay K and other components, and the circuit is shown as the chart 1. AC 220V voltage is bucked by T, rectified by VD1 ~ VD4 and filtered by capacitor C1 to provide DC 12V voltage (Vcc) for IC as the operating voltage. R1 ~ R4 select l/4W or 1/8W carbon film resistors. Cl chooses the aluminum electrolytic capacitor with the voltage in 16V; C2 and C3 select monolithic capacitors. VD1 ~ VD5 use 1N4007 type silicon rectifier diodes. V uses C8050 silicon PNP transistor. K selects JRX-13F 12V DC relay.
