Simple Water Level Indicator With Buzzer Circuit Diagram. Water Level indicator with auto cut off circuit In this circuit we have used a relay instead of a buzzer as the tank will become full relay will be changing its state and will cut off the power. This simple water level indicator will activate an active buzzer eg.

Here is a tutorial of a simple and handy DIY water level buzzer circuit. The tank has 9 conductive type sensors other types of sensors have been mentioned earlier but in our project only. Each transistor is switched on to drive the corresponding LED when its base is supplied with current.
Here we have created 4 levels low medium high and full we can create alarms for more levels.
This happens when rising or dropping water levels come in contact with the respective water sensors arranged step wise inside the water tank at different depths. The circuit is based on 5 transistor switches. This circuit is simple and inexpensive as it using only a few parts like Transistor buzzer resistor and a power supplybattery. This simple water level indicator will activate an active buzzer eg.
