XENSIV™ 60GHz BGT60TR13C Radar System on Module MCU4
Set and get configuration
[1 to 4]
calibration message output. Selection is 1
to 4. For example, setting the value to 4 would change the output
message rate to 4 Hz.
Set presence detection detect mode.
Flash; default is macro then micro.
Macro then micro: The radar would first detect macro motion for
presence, and enter micro motion detect mode when the object
movement is smaller.
Macro only: Radar would only detect macro movement.
Micro only: Radar would only detect micro movement.
Macro and micro: Radar would always detect both macro and micro
movement; either kind of motion exceeding the threshold would be
treated as a presence.
Enable/disable active output command of range bin profile. A range
bin profile would output periodically (1 s) when enabled. The range
bin profile is an array of floating numbers showing the received signal
level (in dB) at different distances. This feature can be used to
measure the RF attenuation due to plastic casing.
[0.00 to 10.2]
Get or set the minimum detection distance for presence detection.
The user needs to ensure this value is smaller than the maximum
range. The setting would be stored in Flash; default is 0.00 m.
[more than 0.0]
in macro movement detection. After changing
this value, the sensitivity would be customized. The setting would be
stored in Flash; default is 1.00.
[more than 0.0]
in micro movement detection. After changing
this value, the sensitivity would be customized. The setting would be
stored in Flash; default is 25.00.
[0.5 to 30.0]
motion is no longer macro
movement. For example, if the value is 1, it means a detected value
below the macro threshold for 1 s continuous would be treated as no
macro movement. The setting would be stored in Flash; default is 1.
[1.5 to 1800.0]
the motion is no longer micro
movement. The judging criteria are the same as for a valid macro
value. The setting would be stored in Flash; default is 4.
[1 to 64]
Get or set the macro trigger
range for macro movement detection.
When setting a higher value, the user needs to enter the inner
detection zone to trigger a presence. The value is a multiple of 0.33 m.
The setting would be stored in Flash; default is 1.
[0 to 255]
Get or set the trigger delay for macro movement detection. Input
value is multiple of 0.25 s. For example, by setting the value to 3, the
radar will determine the motion as macro movement for a continuous
0.75 s of major motion. The setting would be stored in Flash; default
is 0.
[1 to 16]
Get or set the number of chirps per frame for coherent integration.
Setting a higher value, radar will send out more chirps in a frame and
use them for coherent integration and interference checking,
resulting in a better signal-to-noise ratio. Note that power
consumption will increase for setting a higher value, as the RF active
time will also increase. The setting would be stored in Flash; default is
16.
