The agricultural automatic water valve circuit is composed of the power supply circuit, detection circuit and control circuit, and the circuit is shown as the Figure 1. Power supply circuit is composed of the power transformer T, rectifier diodes VD1 ~ VD4 and filter capacitor C1 and so on. Detection circuit is composed of the high water level detection electrode a, low water level detection electrode b and water inlet pipe detection electrode c and so on. Control circuit consists of the time-base integrated circuit IC, relay Κ and the external components. R1 ~ R3 use 1/4W or 1/8W metal film resistors. VD1 ~ VD5 use 1N4001 or 1N4007 silicon rectifier diodes.
