During installation, avoid metal and other objects blocking the transmission of electromagnetic waves in
front of the module to block the antenna.
Different housing materials and the distance between the module and the inner surface of the housing will
result in different spectral energy returned and parameter settings, which need to be fine-tuned according
to actual conditions. It is generally recommended that the module be 5-6mm away from the housing,
which can be adjusted according to the actual measurement.
We recommend users to test according to the default settings of the module. If the effect is not as
expected, you can send the shell structure to the original factory, and the original factory will test
and adjust a reference setting.
It is recommended to use plastic as the casing, because the radar is a very sensitive module in the
presence of the human body. If the casing is made of a material with large attenuation, it may
affect the detection.
If the person under test sits quietly with his back to the radar, the sensing effect will decrease. The
rise and fall of the chest or abdomen caused by breathing cannot be detected when the back is
facing the radar.
Install to avoid the air outlet of the air conditioner, fans and other objects. Shaking equipment and
objects may be detected by radar to determine the presence of persons.
When multiple modules are installed and used at the same time, the distance between the modules should
be greater than 0.5 meters, and the antennas of different modules should not face each other.
According to user scenarios, the sensitivity is adjustable. Users can adjust the sensitivity according
to their actual application scenarios. The sensitivity settings given in this manual can be used for
users' reference. The FOV given in the manual is only for our test environment, and the actual FOV
may deviate due to different actual scene environments or factors such as housing.
