4.!Static Protection
Radar products have electrostatic sensitive circuitry and are susceptible to
electrostatic hazards, therefore they need to be adequately protected from
static electricity during transport, storage, work and handling. When handling
radar sensors, please wear anti-static gloves if possible.
5.!Functional disturbances
5.1 Unoccupied state, abnormal output occupied
In normal conditions, the radar will accurately determine the presence of a
sitting or sleeping body and output information on falls, breathing, vital
signs etc.
A. Radar scanning area is large, doorway, boarded wall next door
movement is detected
Adjustment method: reduce radar sensitivity, radar provides scene setting
B. Radar underneath is facing a running air conditioner or fan
Adjustment: adjust the radar position so that it is not directly in front of
the air conditioner or fan
C. Shifting objects caused by air conditioning winds
Adjustment method: cotton, non-metallic objects will not cause false
alarms, metal objects need to be fixed
D. The radar is not fixed, vibration causes false alarms
Avoid supporting shaking and vibration
E. Occasional moving objects such as pets, birds, etc.
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
