How do you know when it s empty.
Arduino oil tank level sensor.
2 i put const int area1 10000 for my 1 tone square tank and i got the results i need.
The ping sensor measures distance using sonar.
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.
Measure fuel level with arduino.
1 correct me if i am wrong but i should place the sensor 20cm above my tank maximum level.
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.
We hope you found this project useful.
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.
The circuit also monitors the level of water in the sump tank source tank.

Just solved 3 the sensor must be very well placed above the water or ground if you are testing.
My tank looks like the one in the photo.
Download circuit diagram and programming.
Fuel tank level gauging.
Finally we have completed the water level sensor arduino tutorial.
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.
