1. INTRODUCTION
The MM5D91-00 is the presence detection sensor module which integrates 60GHz
mmWave technology. The module simplifies the implementation of mmWave sensors in
the band of 61.0 to 61.5GHz, and it includes the ARM Cortex-M4F based processor
system, 1Tx 3Rx antenna and onboard regulators. This presence detection sensor module
targets low power and high resolution presence detection in smart home, office, security
and diverse applications.
The Jorjin mmWave Radar sensor evaluation kit MM5D91E00 shows as below. Based
on the MM5D91-00 Radar sensor module, evaluation board is built to demonstrate the
function of presence detection of the 60 GHz radar sensor with its sophisticated radar
presence detection algorithms. This evaluation kit is easy for demo and development for
customer.

3.2. Set and Get Configuration
User can set or get the configuration of the radar at the Config tab page. Currently
following items are available:
Item
Description
Version
Get the firmware version in MCU.
Max range
[ 0.66 –10.2 ]
Get or set the maximum detection distance of presence detection.
Setting would store in flash, default is 1.00m.
Sensitivity
Get or set the sensitivity level presence detection, higher
sensitivity means more sensitive to small movement. Changing
sensitivity would change the Macro and Micro threshold value.
Setting would store in flash, default is medium.
Note: User is recommended to use high sensitivity setting for optimal performance at
angles and for use cases such as a person sitting on a chair behind the table.
Get presence event
Get current presence detection result.
Presence detect on/off
Set presence detection on or off. Default is on. When set to off,
radar chip power would also set to off.
RFCW mode
Enable or disable the RF continuous wave mode for FCC test.
Presence detection needs to be off before enabling this mode.
Disable: Disable RFCW mode.
-Low: Set RFCW output at 61.02GHz
-Mid: Set RFCW output at 61.25GHz
-High: Set RFCW output at 61.48GHz
-Low TX off: Set RFCW test at 61.02GHz with TX off
-Mid TX off: Set RFCW test at 61.25GHz with TX off
-High TX off: Set RFCW test at 61.48GHz with TX off
Temperature
Get temperature on radar chip (°C)
Sleep mode
Set the radar module into deep sleep mode. The module would
wake up again when data received at UART RX pin. A preamble
byte such as 0x00 is needed to add in the next command to have
the command correctly received at the module (to compensate
wakeup delay time).
Detect mode
Set presence detection detect mode. Setting would store in flash,
default is Macro then micro.
-Macro then micro: Radar would first detect macro motion for presence, and enter
micro motion detect mode when the object movement becomes small.

-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 one kind of motion exceeding the threshold would be treated as presence.
Min range
[ 0.00 –10.2 ]
Get or set the minimum detection distance of presence detection.
User needs to ensure this value is smaller than Max range. Setting
would store in flash, default is 0.00m.
Macro threshold
[ > 0.0 ]
Threshold value using in macro movement detection. After
changing this value, Sensitivity would become customize. Setting
would store in flash, default is 1.00.
Micro threshold
[ > 0.0 ]
Threshold value using in micro movement detection. After
changing this value, Sensitivity would become customize. Setting
would store in flash, default is 25.00.
Macro valid
[ 0.5 –30.0 ]
Timeout value (second) using for judging the motion is no longer
macro movement. For example, if value is 1, it means detected
value below macro threshold for continuous 1 second would be
treated as no macro movement. Setting would store in flash,
default is 1.
Micro valid
[ 1.5 –30.0 ]
Timeout value (second) using for judging the motion is no longer
micro movement. Judging criteria is same as in Macro valid value.
Setting would store in flash, default is 4.
Macro trigger range
[1 - 64]
Get or set the macro trigger range for macro movement detection.
Setting a higher value, user need to enter the detection zone inner
to trigger presence. Value is multiple of 0.33m. Setting would store
in flash, default is 1.
Macro trigger delay
[0 - 255]
Get or set the trigger delay for macro movement detection. Input
value is multiple of 0.25s. For example, setting value to 3, radar
will determine the motion as macro movement for continuous
0.75s of major motion. Setting would store in flash, default is 0.
Chirp per frame
[1 - 4]
Chirp per frame of presence detection. Setting a higher value,
radar will send out more chirps in a frame and use for coherent
integration, resulting in a better signal to noise ratio. Notice that
power consumption will also increase for setting higher value, as
the RF active time will also increase. Setting would store in flash,
default is 1.
Unique ID
Get the unique ID of the module.
Reset config
Reset all setting storing in flash to default.

After pressing Set or Get button, the relevant binary command would be shown in the command
textbox. Developer can use that command for reference or checking. The temperature button can
enable periodic polling of the radar chip temperature.

3.3. Presence event output
When event control is turned on, the presence detection result would be shown at Event tab page.
Item
Description
Presence Event
Presence detection result.
-IN: moving object detected in the zone
-OUT: no moving object detected in the zone
Distance (m)
Detected distance range of the closest moving object, in meter.
Time (s)
Relative event time, in second. This is the time starting from ower
on, not an absolute time.
Received event command would be shown in the command textbox for reference.

3.4. Firmware update
Firmware update can be done in the Firmware update tab page. Select the target .bin file by
pressing Select button. Bootloader mode would be entered automatically during the update process.
In case a non-working firmware is loaded, user can manually force the module to enter bootloader
mode by pressing the user button on the mother board after power up or reset. The LED would change
to blue color when bootloader mode is entered.
Then press Flash button to start the firmware update. Whole update process would take around 30
seconds. Although protection mechanism is added in the update process, it is recommended not
unplugging the USB or power off the board to prevent any unexpected error.
