Arduino Oil Tank Level Sensor

Fuel tank level gauging.

Arduino oil tank level sensor.

How do you know when it s empty. A beep sound is generated when the level in the sump tank is low or if there is any fault with the sensors. 1 correct me if i am wrong but i should place the sensor 20cm above my tank maximum level. 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. 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.

Support this channel on patreon. My tank looks like the one in the photo. Now your lcd screen or serial console should be showing the water level. 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.

Download circuit diagram and programming. We hope you found this project useful. 2 i put const int area1 10000 for my 1 tone square tank and i got the results i need. Finally we have completed the water level sensor arduino tutorial.

As the tank empties the float drops and slides a moving contact along the resistor increasing its resistance 2 in addition. The circuit also monitors the level of water in the sump tank source tank. Oil tank level control.
