Hi people,
I am working on a water level project to check, how much water I have in my tank and I had the idea of using something like the float in the below link, which is usually used for fuel tanks in cars.

My main problems are that I don't know if I can use such thing with 5V or what Output would this give me. I don't want to use sensors which have a digital output and this is why I am coming up with such idea as I need a linear voltage output, similar to the LM35 like in the below link graph.

I also tought of hooking up a float to a variable resistor, but I don't know If I will be getting a linear graph as someone has told me that, thats not linear even when using single turn potentiometer.
Thanks in advance.

FiatUno
