The agricultural automatic water supply device circuit is composed of supply circuit, water level measuring control circuit, water protection outage circuit and pump motor starter operation circuit, the circuit is shown in Figure 1. Power circuit is composed of fuse FU1, power transformer T, rectifier diodes VD4 ~ VD7, filter capacitors C4, C5, and three-terminal voltage regulator integrated circuit IC. Water level measuring control circuit consists of water level detection electrodes a ~ c, resistors R1, R2, capacitors C1, C2, transistors V1 ~ V4, diodes VD1, VD2 and relays K1, k2. Water protection outage circuit is composed of the detection electrodes A, B, resistor R3, capacitor C3, transistor V5, composed of diodes VD3 and relay K3. Pump motor starter operation circuit is composed of knife switch Q, fuse FU2, control buttons S1, S2, AC contactor KM1 ~ KM3, time relay KT and pump motor M. AC 220V voltage is bucked by T, rectified by VD4 ~ VD7 , filtered by C5 and stabilized by IC to provide +12 V voltage for the water level measuring control circuit and water protection outage circuit.
