How Does The Radar Click Board™ Work?
The Radar Click Board™ as its foundation uses the MM5D91-00, a presence detection sensor module with an integrated mmWave technology from Jorjin Technologies Inc. It counts the number of people entering or exiting an entrance, simplifies the implementation of mmWave sensors in the band of 61.0 to 61.5GHz, and includes the ARM Cortex-M4F-based processor system 1Tx 3Rx antenna and onboard regulator. This Click board™ is built to demonstrate the function of the entrance counter of the 60GHz radar sensor with its sophisticated radar presence detection algorithms.
Characterized by low power consumption and high resolution, this board represents a suitable solution for various presence sensing applications, from office and home to commercial buildings and more. Its detection range goes up to 10m for macro motion, representing human movements, and 5m for micro motion, which stands for stationary human (normal breathing and blinking eyes) in sitting or standing positions with no active signs for at least 30 seconds. Immune to environmental factors such as temperature, wind, sunlight, and dust/debris, the MM5D91-00 also comes with azimuth and elevation field of view of ±45° and ±40°.
The MM5D91-00 communicates with MCU using the UART interface with the default baud rate of 115200bps for the data transfer. In addition, it also uses several mikroBUS™ pins. An active-low reset signal routed on the RST pin of the mikroBUS™ socket activates a hardware reset of the radar module. It also has three general-purpose pins, routed to the AN, PWM, and INT pins of the mikroBUS™ socket marked as GP2, GP1, and GP0 to signal an essential change in device status, alongside its green, red, and blue LED indicators. Green LED stands for active presence indication, while red LED represents non-presence indication. Blue LED serves for bootloader mode indication.
The Radar Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.

Software Support
We provide a library for the Radar Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description
This library contains API for the Radar Click Board™ driver.
Key functions
-
radar_get_eventThis function waits for an IN/OUT event or ACK command response. -
radar_get_temperatureThis function reads the chip internal temperature. -
radar_set_detection_rangeThis function sets the min and max presence detection values.
Example Description
This example demonstrates the use of the Radar Click Board™ by reading and parsing events as well as the module internal temperature.

if ( RADAR_CMD_ID_DETECT_IN_EVT == evt_id )
{
log_printf( &logger, " EVENT: INrn" );
radar_float_bytes_t distance;
memcpy ( distance.b_data, &evt_payload[ 8 ], 4 );

log_printf( &logger, " Target distance: %.3f mrn", distance.f_data );
memcpy ( distance.b_data, &evt_payload[ 12 ], 4 );
radar_float_ieee_to_mchip ( &distance.f_data );
log_printf( &logger, " Accuracy (+/-): %.3f mrn", distance.f_data );
}
else
{
log_printf( &logger, " EVENT: OUTrn" );
}
uint32_t evt_time = ( ( uint32_t ) evt_payload[ 3 ] << 24 ) | ( ( uint32_t ) evt_payload[ 2 ] << 16 ) |
( ( uint16_t ) evt_payload[ 1 ] << 8 ) | evt_payload[ 0 ];
log_printf( &logger, " Elapsed time: %.2f srn", evt_time / 1000.0 );
float temperature;
if ( RADAR_OK == radar_get_temperature ( &radar, &temperature ) )
{
log_printf( &logger, " Temperature: %.2f Crnn", temperature );
}
}

Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
MIKROSDK
The Radar Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
