Description

Circuit schematic like in Figure 1 above is Circuit Schematic Automatic Water Pump Controller using 555 Timer. Eleccircuit site describe that the IC 555 works in the astable multivibrators. For signal generators to activate the transistor, which is used to drive relays – off the pump.

Assuming flood level to the test point C. (Will has flooded all the time.) But the water level has not reached the test point B. These parts to be IC1, Q1, Q2 (2SD882) and RY1 will not work. So the contacts of RY1a and RY1b be connected to the terminal NC, the 220 volt AC electricity can be supplied to the pump. The waters pump start to pump water into the tank..
