How do you know when it s empty.
Arduino oil tank level sensor.
Fuel tank level gauging.
Support this channel on patreon.
My tank looks like the one in the photo.
A beep sound is generated when the level in the sump tank is low or if there is any fault with the sensors.
If the level in side the sump tank is low the motor will not be switched on and this protects the motor from dry running.
This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank.
Just solved 3 the sensor must be very well placed above the water or ground if you are testing.
The circuit also monitors the level of water in the sump tank source tank.
Oil tank level control.
1 correct me if i am wrong but i should place the sensor 20cm above my tank maximum level.
We hope you found this project useful.
The sensing unit usually uses a float connected to a potentiometer typically printed ink design in a modern automobile.
Finally we have completed the water level sensor arduino tutorial.

2 i put const int area1 10000 for my 1 tone square tank and i got the results i need.
An ultrasonic well above human hearing pulse is transmitted from the unit and distance to target is determined by measuring the time required for the echo return.
As the tank empties the float drops and slides a moving contact along the resistor increasing its resistance 2 in addition.
Now your lcd screen or serial console should be showing the water level.
The ping sensor measures distance using sonar.
