Hello,
I'm building a new board in order to measure water pressure using some sensors which would provide a variable resistance depending on the level of pressure of water in a pipe.

Electrically they're not so different from a potentiometer, the problem is that the R value is so low (range from 86 to 330 Ohm) that the classic RCtime schema cannot be applied.
I need at least 8 bit resolution from low to high range.

Could you please suggest me the best schema to connect such sensors to a 16F877A?

Thanks
