Ranging drift with temperature

When the temperature increases, the ranging value is affected by an offset of 1.3 mm per degree Celsius change.

This value is an offset and not a gain, and it does not depend on the target distance.

The device embeds a feature that allows to compensate the temperature variation effect.

When the ranging is started, a self-calibration is performed once and this allows to remove the ranging drift.

In order to get the most accurate performances, perform a self-calibration when temperature varies. To self-

calibrate, call the functions “stop” and “start”, in sequence.
