Concept:
- This water level sensor will be used for water tank to check where the water level is.
- Every time the water get poured, an LED light will blink to show the status of the water in the tank.
- Once the sensor is fully filled, it will ring a buzzer stating that the water tank is full and will not require more water.
- This will help stop the overflowing of the tank.
Working principal of water level sensor:
The working principle of the water level sensor is that when it is put into a certain depth in the liquid to be measured, the pressure on the sensor’s front surface is converted into the liquid level height.
COMPONENTS REQUIRED:

Code:
Setup:
- Set up the LED pin and connect them to digital pin numbers 2,3 and 4.
- Connect the ground pin up arduino to breadboard.
- Connect the positive buzzer to digital pin 5 and negative to the negative breadboard.
- At last, we connect the water level sensor.
- In water level sensor, the “S” i.e signal positive is connected to analog input A0.
- The positive will connect to 5v and the negative to ground of arduino.
- Plug in your arduino uno board into your PC and select the correct board and COM part.
- Open up serial monitor and set your baud to 9600 baud.
- Verify and upload your sketch.
