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. The detection circuit is composed of the water level probe and resistor R3 and so on. Control circuit consists of transistors V1, V2 and the relay K and other components. AC 220V voltage is bucked by T, rectified by VD1 ~ VD4 and filtered by C1 to produce DC voltage with about 24V for the control circuit. R1 ~ R3 select 1/4W carbon film resistors. VD1 ~ VD5 select 1 N4007 silicon rectifier diodes.
