In this electronics project, 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
