STHS34PF80 - Clarify what is presenceVal cm^-1

Components & Accessories

STHS34PF80 board - I’m experiment with mainly detecting a presence,
human or other, e.g. animals – not moving.

ARDUINO – One of the return value from Example1_BasicReadings.ino is presenceVal cm^-1 (Serial.print(presenceVal):wink:

My question:

What does values of presenceVal represent?

(I check the library and source code, but still I’m not sure or clear the what it is)

Thanks

I do not have one of these to check with but I would imagine this value quantifies how much of a presence is detected in front of the sensor?

Good guess, though from testing, I may sit, not moving and the values are changing from ~500 to 1500. I was thinking that presense will be represented by 0 or 1 (too simple..), but must be other reason(s) for presence range.
