Finally we have completed the water level sensor arduino tutorial.
Arduino oil tank level sensor.
Measure fuel level with arduino.
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.
If you have a fuel or water tank that is either metal or colored plastic you may have run into the same problem i had.
1 correct me if i am wrong but i should place the sensor 20cm above my tank maximum level.
The ping sensor measures distance using sonar.
Now your lcd screen or serial console should be showing the water level.
We hope you found this project useful.
As the tank empties the float drops and slides a moving contact along the resistor increasing its resistance 2 in addition.
How do you know when it s empty.
This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank.
2 i put const int area1 10000 for my 1 tone square tank and i got the results i need.
Fuel tank level gauging.
Leave a comment below if you have any doubts or queries.
Download circuit diagram and programming.
My tank looks like the one in the photo.
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.
Just solved 3 the sensor must be very well placed above the water or ground if you are testing.
The sensing unit usually uses a float connected to a potentiometer typically printed ink design in a modern automobile.
