In order to ensure the normal operation of the module's internal VCO
circuitry, the power supply to the module is required to be +5V to +6V
with a voltage ripple of ≤100mV.
The external power supply must provide sufficient current output
capability and transient response.
8. Common problems
Interference factors: Radar is an electromagnetic wave detection sensor
and moving inanimate objects can lead to false alarms. Movement of
metals, liquids, can lead to false positives. Often, electric fans, pets close to
the radar and the swaying of metal curtains can cause false alarms. Radar
needs to be planned at the angle of installation.
Non-interference factors: Radar electromagnetic waves can penetrate
human clothing, curtains, thin wooden panels, glass. Depending on the
application, the installation angle and performance of the radar needs to
be determined.
Semi-interference factors: Radar determines the presence of the human
body and is not suitable for direct exposure to air conditioners. Internal
motors in air conditioners can cause radar miscalculations. Radar products
should not face the air conditioner directly. Or in the same direction as the
air conditioner.
