 Configuration directives

th1=**, set the motion detection sensitivity. Integer setting. The default configuration is th1=120. The higher

the value, the less sensitive the module is. The sensing distance and range are smaller. The FOV under the reference

sensitivity setting is given later.

th2=**,set the presence detection sensitivity. Integer setting. The default configuration is th2=250. The higher the value,

the less sensitive the module is to presence detection. The sensing distance and range are smaller. The FOV at the reference

sensitivity setting is given later. Generally, the sensitivity can not be adjusted.

dtime=**, set the GPIO delay detection time. Integer setting. The default configuration is dtime=5. A value of 5

is 5S.

mov_sn=**, set the GPIO to pull up the GPIO when it detects several large-scale data. The default

configuration is mov_sn=3, the larger the setting, the less sensitive it is, and it can be increased when there are large

false positives.

occ_sn=**, set how many times small amplitude data is detected after GPIO is pulled high to maintain GPIO

high level. The default configuration is occ_sn=5, the larger the setting, the less sensitive it is. It is not recommended

to increase it.

save, save the parameter settings. If save is not sent, the power-down will fail.

get_all, the module outputs the current parameter settings.

All commands sent with carriage return and line feed are valid.

 Radar output

When the radar detects a larger motion, it outputs mov, ******. (The second number represents the signal strength)

When the radar detects the static state of the human body or small amplitude movements, it will output occ, ******. (The

second number represents the signal strength)

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. (The first number represents the spectral line position, the

user can ignore it directly)

Note: The startup time of the module is about 15 seconds, and it starts to output data after 15 seconds of

power-on. Because the module makes existence judgment by accumulating signal characteristics for a period

of time, when the person disappears from the radar detection range, the radar will continue to accumulate

signals for a period of time, so the radar will stop outputting after a period of lag time.
