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 debugged with the test mode. Generally, it is recommended that customers test according to

the default parameters. If you encounter problems, please consult our technical staff.
