Re: [sensors] the near/far event names

Not all sensors are created equal.  They report at different resolutions, they report different ranges.  Because of this, you can't just hand back percentages.  It has to be clear that percentages will not tell you enough.  If I say my ambient light level is 42 %, what does that mean?  Does it mean that it is dark in my room?  To know this, you will need to know more about my senor.  You will need to know the min and max, and therefore the value to make any sense of that percentage number.

Hope this helps.

What use cases do you foresee, or have in mind, for these numbers?
