Simple Water Level Control

this is a simple projects for beginners in electronics. this is a water level controller using simple components. i used this to control my house pump.

tip 122 transistor - 2 pieces

1000uf/2200uf capacitor - 2 pieces

pcb

4 pieces 5v relay

powers supply - 7.5v

this circuit is very simple make liquid switch with 2nd diagram. and use it in the place of both float switch in this way that both wires from float switch is connected to relay of liquid switch in this way +5v into com and no on other end. now you are finished test it.
