Setting 18: Sensor sensitivity (advanced)
Set sensor sensitivity
X is a value between
1-250
and its default value is
50
. It
indicates the duration of a light measurement cycle in
steps of 0.1mS.
The higher the X value, the longer the duration, the more
sensitive the sensor will be to light. The lower the X value,
the shorter the duration, the less sensitive the sensor will
be to light.
Example: if the output of a raw light measurement is 255
and X is decreased to 10, the Raw light value will decrease
as well (e.g. to 210). So the less sensitive, the lower the raw
light value will be in the same light conditions.
Example: if the output of a raw light measurement is 0 and
X is increased to 150, the Raw light value will increase (e.g.
to 20). So the more sensitive, the higher the raw light value
will be in the same light conditions.
When the sensor is set the auto-calibration (setting 4:3),
the sensor will continuously auto-calibrate by automatically
adjusting the sensor's sensitivity (setting 18).
This is done in such a way that in case of a place-back the
raw light value is just below the "dark calibration threshold"
(
setting 14, default 25
) and in case of a pick-up the raw
light value is just above the "bright calibration threshold"
(
setting 15, default 225
).
For example: in case the raw light value is 255, the sensor
will automatically decrease the sensitivity until the light
value will be just above 225. Vice versa, in case the raw
light value is 0, the sensor will automatically increase
the sensitivity until the light value is just below the "dark
threshold (default 25).
