For my plan-A I hooked up the sensor to a circuit I cobbled together out of a 358 dual Op-amp. The first op amp establishes 1v from the 5v source. The second op amp acts as a differential amplifier that amplifies the difference between the 1v and the 1.45-1.77v signal and outputs 1v-5v. (Plan B 1-25v). I'm using STP shielded twisted pair for the wiring and grounding it. Plan C is the one below -- extend i2c with the range extender. I'm on the plane to go install this into the factory now... | |
