Re: Circuit help
I suppose you are using the float
as a mean to turn the variable resistor.
If you can already sense the resistance,
you can power up the variable resistance,
and obtain the varying voltage.
This voltage can be a mean of indicator
to indicate the liquid level.
If you need to obtain a digital output,
you can use a ADC (analog to digital converter),
so that the information can be process by a computer.
Else you can interface the varying voltage to a circuit
which you might want to display directly.
