Tank Water Level Indicator.

You may have bad experiences having forgotten to close the water valve and wasting water and money 😉. Or you nay have a bad experience having forgotten to fill the water tank and no water situations.

I know that you will realize this is not an complex circuit but this is very useful to solve those issue in your real life.

Since it is a simple circuit, shall we move to the project.

The circuit is based on 4 transistors and the out out is given by 4 LEDs. Following are the required parts.

  • 2N2222 Transistors

  • 120 ohm Resistors

  • LEDs

  • Wires and cables.
  • a PVC pipe

The circuit is given below.

Watch the following video for more details.
