 ABS Water Level Indicator with Alarm on Tank Full with 5 Sensors

  I have made a simple Water Level Indicator with buzzer. To make this automatic water tank level indicator circuit I have used only BC547 NPN transistors so no IC is required.

The alarm will automatically start when the water reaches the maximum level.

Required Components for this BC547 project

1. 1k Resistors 4no (R1, R3, R5, R7)

2. 10k Resistors 4no (R2, R4, R6, R8)

3. BC547 NPN Transistors 4no

4. 5-mm LEDs 4no

5.DC Buzzer (5V)

6. Switch

7.Terminal connector

8. 5V DC Supply

Here I have used the 5V DC supply, but if you want to use the 12V DC supply, then connect a 12V DC buzzer. No other changes are required in the circuit for 12V.

  I have also explained how to make this liquid level monitoring circuit on the homemade PCB. And also shared the PCB Layout so, you can make this water level sensor using buzzer circuit on the plastic sheet.

You can use this circuit in any overhead or underground water tank to measure the water level. This simple homemade project is very useful to save water and electricity.
