Radar output
When the radar detects a larger motion, it outputs mov, dis=***.
When the radar detects the static state of the human body or the movement of a small amplitude,
it will output occ, dis=***. dis represents the target distance, in meters.
When the radar cannot detect the target, it stops outputting. The user can make a certain delay in
the upper layer to avoid frequent unmanned state when the signal is weak.
Configuration directives
rmax=**
，
Set the maximum detection distance. The distance value with one decimal place
can be set, and the unit is meters. For example: Set the module to only detect targets within a
distance of 6 meters. Then send rmax=6, at this time the module will only output the target
within 6 meters. Targets 6 meters away will not output. The module defaults to rmax=6.
mth1=**
，
Set the segmentation sensitivity threshold of 1. mth1 corresponds to the signal
threshold within 2.8 meters. The default value is 60.
mth2=**
，
Set the segmentation sensitivity threshold of 2. mth2 corresponds to the signal
threshold within 2.8-8 meters. The default value is 30.
mth3=**
，
Set the segmentation sensitivity threshold of 3. mth3 corresponds to the signal
threshold beyond 8 meters. The default value is 20.
The larger the sensitivity value, the less sensitive the module is. The main reason for segment
sensitivity is that the reflected signal of the short-range target will be relatively stronger, so the
same sensitivity as the long-distance target is not required at short distances. At the same time,
according to different environments, you can also make targeted settings. The segment
sensitivity can be debuggedwiththetestmode.Generally,itisrecommendedthatcustomerstestaccordingto
