If US-D1 is used outside of its Maximum
Operational Altitude(Table 1). Inconsistent
small readings will be output(See Figure 4
below).
For full confidence,
only consider US-D1’s
data when used within
its operating range
Altitude data from US-D1 may have various
step-size, since some post-processing algorithm
is implemented after radar processing, e.g.
averaging, filtering.
No action needed
Altitude data from US-D1 may give unexpected
or incorrect measurements under operation in
an indoor environment. Multipath reflections of
the sensor’s radio waves are complicated in
enclosed environments and may therefore
introduce errors in the radar’s processing.
DO NOT rely on US-D1
in an indoor, tightly
enclosed environment
