'Solving a digital offset with amplification
In talking to a range of digital sensors, I keep running into a problem of them occasionally offsetting. That in itself isn't a problem, as it can be explained by missed timing (think 200 ft. of cable connected to a DS18B20 temperature sensor): a 1 becomes a 0, or vice versa (a 40 becomes 168).
But I'm running into a condition where it's amplifying at the same time as offsetting, e.g., sensor A was "2", sensor B was "5", so a difference of 3 between them; when offset, the difference appears to be multiplied by the offset.
Example: sensors all @ ambient in a cement column (gradient normal)
This is definitely happening in the digital domain. Any suggestions?
