Table 7: Raw detection table description
Field
Description
Segment (Seg)
Beam segment in which the object is detected.
Distance
Position of the detected object.
Amplitude
Quantity of light reflected by the object and measured by the module.
Flags
8-bit status (bit field). See Table 8.
The Flag parameter provides the status information that indicates the measurement type.

3
Normal measurement
Received signal is above the saturation level.
Measurements are valid (VALID is set) but
have a lower accuracy and precision.
Consider decreasing the light source intensity.
