Automatic water level controller for submersible pump without ic

[Aman bharti]

 This is an Automatic submersible Motor controller circuit using transistor

•  The Main Advantage Of this Project Is To All Three LEDs Are Glowing One by One. Only One LED is Glowing At One Level And Other Two Are in Off state.

Below is a modified ckt that has advantage of Motor will Again start only if the water level goes to less than half

Sir,  this circuit does not suit my purpose because my submersible pump has separate START and STOP switches which are activated for a few seconds to operate. Please help.

you connect the circuit before the starter, i mean the supply to the motor starter pass through this circuit Relay.

You start the motor using start switch ,when tank will full, then automatic stop the motor.
