As the radar measures micro-movements, the sensitivity is very high and
this interference cannot be excluded.
F. Power supply interference, resulting in occasional false alarms.
Try to keep the power supply current stable and reduce ripple.
5.2 Manned status, abnormal output unoccupied
Radar determines the presence of a human body by sending and receiving
electromagnetic waves. The closer you are to the radar, the more accurate it
is.
A. Human body out of radar range
Radar scanning range with adjustment of mounting angle. Radar
measurement range, in different environments with different electromagnetic
wave reflection areas, the scanning area will vary slightly.
B. False output due to metal occlusion
Excessively thick desks and chairs, metal seats. It will block the
electromagnetic wave penetration and cause misinterpretation.
C. Differences in scanning angles
The radar does not scan the torso area. This can lead to false positives.
D. Radar sensitivity is too low
The radar offers parameter adjustment to increase sensitivity for
improvement.
