Microwave 6 Click is a compact add-on board that utilizes the Doppler Shift Phenomenon to sense motion. This board features the PD-V8-S, a high-frequency microwave sensor from Ningbo Pdlux Electronic Technology. The transmitter on this transceiver works on a 5.8GHz frequency over the patch antenna, with a 2-3kHz pulse repetition frequency. The strength of the sensor’s output, in other words, the detection range, depends on the Signal-to-Noise ratio.

We provide a library for the Microwave 6 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for Microwave 6 Click driver.
microwave6_cfg_setup
Config Object Initialization function.
void microwave6_cfg_setup ( microwave6_cfg_t *cfg );
microwave6_init
Initialization function.
err_t microwave6_init ( microwave6_t *ctx, microwave6_cfg_t *cfg );
microwave6_read_raw_adc
Microwave 6 read raw ADC value function.
err_t microwave6_read_raw_adc ( microwave6_t *ctx, uint16_t *raw_adc );
microwave6_read_voltage
Microwave 6 read voltage level function.
err_t microwave6_read_voltage ( microwave6_t *ctx, float *voltage );
microwave6_set_vref
Microwave 6 set vref function.
err_t microwave6_set_vref ( microwave6_t *ctx, float vref );
This example demonstrates the use of the Microwave 6 Click board™ by reading and displaying the results of AD conversion and motion detection.
The demo application is composed of two sections :
The initialization of I2C or ADC module and log UART. After driver initialization, the app calculates the reference ADC value.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
microwave6_cfg_t microwave6_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.

LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
microwave6_cfg_setup( µwave6_cfg );
MICROWAVE6_MAP_MIKROBUS( microwave6_cfg, MIKROBUS_1 );
err_t init_flag = microwave6_init( µwave6, µwave6_cfg );
if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_printf( &logger, " Calibrating the sensor...\r\n" );
log_printf( &logger, " There must be no movement near the sensor!\r\n" );
log_printf( &logger, "----------------------------------\r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
if ( MICROWAVE6_OK == microwave6_read_voltage( µwave6, &reference ) )
{
log_printf( &logger, " The sensor has been calibrated!\r\n" );
log_printf( &logger, " Detector AN Voltage : %.3f[V]\r\n", reference );
log_printf( &logger, "----------------------------------\r\n" );
Delay_ms ( 100 );
}
else
{
log_error( &logger, " Communication error." );
for ( ; ; );
}
log_printf( &logger, "The motion detector unit is ready.\r\n" );
log_printf( &logger, "----------------------------------\r\n" );
Delay_ms ( 100 );
}
The demo application reads the ADC results, takes an ADC sample, compares the difference between the taken samples and the ADC reference value, and reports the movement if the difference is higher/lower than the selected threshold value. Results are being sent to the UART Terminal, where you can track their changes.
void application_task ( void )
{
if ( MICROWAVE6_OK == microwave6_read_voltage( µwave6, &voltage ) )
{
if ( ( ( voltage + MICROWAVE6_THRESHOLD ) < reference ) ||
( ( voltage - MICROWAVE6_THRESHOLD ) > reference ) )
{
if ( MICROWAVE6_FLAG_SET == flag )
{
log_printf( &logger, " Motion detected!\r\n" );
log_printf( &logger, " Detector AN Voltage : %.3f[V]\r\n", voltage );
log_printf( &logger, "----------------------------------\r\n" );
flag = MICROWAVE6_FLAG_CLEAR;
Delay_ms ( 100 );
}
}
else
{
flag = MICROWAVE6_FLAG_SET;
}
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART Click, 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.
Slider click uses SPI bus communication to converts analog input voltage (VCC) to digital output value and shows this result on LED and USB UART terminal. Value of analog voltage depends on the slider position.
[Learn More]Pressure 10 Click features a digital interface barometric pressure sensor, based on piezoresistive bridge, labeled as HSPPAD042A, from ALPS Electric. It can use both SPI and I2C communication protocols, allowing it to be interfaced with a broad range of MCUs. Besides the pressure readings, this Click board™ also offers very accurate temperature reading, which is required for the pressure readings compensation and can be used in a wide range of battery-powered and portable applications thanks to its very low power consumption.
[Learn More]V to Hz 2 click is a device that converts an analog voltage input signal into a pulse wave signal of a certain frequency.
