Automatic Water Level Controller for Submersible Pump and Overhead Tank | 555 Timer Projects 2021

In this mini electronics project, I have shown how to make an automatic water level controller for submersible pump and overhead tank with a 555 timer circuit. This automatic water pump controller also checks the water level of the underground tank, then starts the pump. And there is also an emergency stop switch to stop the water pump.

Here, I have used a 30A relay, so you can easily control up to 1 HP pump with this simple automatic pump controller.

With this simple 555 timer circuit, we can stop the water overflow from the water tank. And the pump will automatically start if the water level becomes low. So we don't need to start and stop the pump manually.

Please note down the following point before making the circuit.
1. Here, I have used 30A Relay, so you can easily control up to 1HP pump
2. For the 3ph pump, you can control the starter with this circuit.
3. Do not coil the water level sensing wires together, keep them separate.
4. The pump will automatically start for the following conditions
Overhead tank water level comes below the "ON" level.
Underground water level above UL1 level.
Manual switch S1 should be in ON position.
5. The pump will automatically stop for the following conditions
Overhead tank water level touches the "OFF" level.
Underground water level comes below UL1 level.
6. If you use a DC pump, then connect the DC supply.
7. For the control circuit you have to give a 12V DC supply.

Please take proper safety precautions while working with the high voltage.

After watching the video, you can easily design this automatic water tank level controller motor driver circuit for your home.
