5. Installation Method and Operating Mode
5.1. Installation Method
It is recommended to install the radar module according to the specific
functions.
5.1.1 Respiration Rate Statistics
For this function, it is necessary to keep the position between the radar and
the chest within the range of 0.5m-1.5m, and expose the chest within the
detection range of the radar antenna.（It is recommended that the radar be
mounted on top or inclined）
5.1.2 Sleep Quality Evaluation
When using the sleep quality assessment or sleep duration recording of the
radar, the installation can only be top mounted or inclined mounted. The radar
installation height is not higher than 2.75m. The installation scene is only
suitable for rest areas such as the bed top of the bedroom.
Note
：
A. For the above different installations, the main radar beam needs to cover the
main activity area of the human body and face the normal direction as far as
possible；
B. When installed obliquely, the horizontal action distance will be reduced due
to the change of horizontal projection of the coverage area；
C. When the module is working, its surface should not be covered by any metal
objects；
D. Affected by the transmission characteristics of electro-magnetic wave, the
radar range is related to the target RCS,the material and thickness of the target
cover, and the radar effective range will change to a certain extent;
E. As for human body detection in static state, different body positions will
affect the effective radar range, we do not guaranteethat all states reach the
maximum perating distance.
