This Project Is Very Useful, Interesting, And Very Effective. This Automatic Water Pump Controller With Three Stage Level Indicator Provides the visual And Attractive LED Indication As Level Of Water in Water Tank. When Tank is Full Then Motor Stops Automatically, In This Circuit No Use Of Any Timer IC.

• This is an Automatic submersible Motor controller

• 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.

In This Project No Need Of Any Capacitor, No Timer IC. A Voltage Regulator IC LM7809, Some Resistors And Some NPN Transistors, Diode, LED And Relay used In This Circuit.

Connect The All Components As Shown In Image Diagram, The Value Of Resistors Are Should Not More Than 2kΩ. And Not Less Than 1kΩ. R8 And R9 Should Not More Than 100 Ω. If All Values Are the same As I Recommend Then Circuit Working Will 100% Successfully. Carefully Connects Terminals Of Transistors And Voltage Regulator ic LM7809. Relay Must Be More Than 20A.

If Q5 BC547 Get Burn Or more Hot, then You Can Use 2N2222.

You Can Use Tricolor Led At The Place Of 3 Different LEDs. But only Common Cathode Tricolor LED. This LED Make its Different Look.
