Automation can make our lives much easier.
For any remote water level controlling, or sand, grains or any other medium, this simple level controller may provide a solution.
It requires basic circuitry knowledge, a bit of soldering experience would be nice. I hope this project may serve to you as a source of inspiration and it would be nice to show if you made a project with it as well.
How does it work?
The system has a tank that is being filled by a 12V water pump. The tank has two switches at two different heights, a lower switch and a higher switch.
When the water level drops below the lower limit switch, the pump is switched on, keeping the relay enabled until the water reaches the higher switch. At this moment the relay is disabled and the pump is switched off.

Floats
To connect the water level to the limit switches, I used some water repellent floats. The limit switches are fixed to the water tank filler opening so that the floats are in the water tank: one float at lower level and one at higher level.
The float levers are made from red spray can tubes. The lower float has a longer lever since it lays at a lower level.
Upper level float and lower level float.
