I am thinking up an idea for a project and I need to keep track of changes in volume of water. The water would be in a water bottle and the sensor could not be inside the actual water bottle. So right now I am thinking of something that would maybe weigh the water bottle? Does anyone have any ideas of how to keep track to changes in volume of water?
I am very new to this all, so things that might seem very basic would probably still be very helpful to me.
