4. Electrostatic (ESD) protection
Radar modules contain electrostatic-sensitive circuits, so they risk electrostatic shocks.
Thus, it is essential to maintain proper electrostatic protection throughout the process of
transportation, storage, work, and handling. Avoid touching the radar module's antenna
surface and connector pins, but hold the corners. We recommend that you wear anti-
static gloves during the operation of the radar sensor.
5. Function interference item
5.1 Unoccupied state, abnormal output occupied
When the radar is in its normal state, it will accurately determine the existence of human
sitting or sleeping states and will output fall data, breathing information, vital signs, etc.
a. Radar scanning covers a large area. You can detect movement around the
doorway and the next door in the wooden wall.
Adjustment method: Reduce radar sensitivity; the radar has scene settings
b. When the radar is facing toward the air conditioner and fan when it is
operating
Adjustment method: Position the radar so it doesn't directly face the air
conditioner and fan
c. Object shaking caused by air conditioning wind
Adjustment method: Cotton and non-metallic items do not cause false
alarms. Metal items should be well-positioned to avoid interference.
d. If the radar is not fixed, vibration may cause false alarms. To prevent this
from occurring, support the radar in a fixed position to avoid vibrations and
shakes.
e. Occasional moving objects, such as pets, birds, or other animals.
Because of the high sensitivity of the radar's detection of micromotions,
this interference cannot be eliminated.
f. Power supply interference can interfere with judgment, resulting in
occasional errors.
Maintain a stable current power supply and minimize ripple.
