Microwave 5 Click is a compact add-on board that utilizes the Doppler Shift Phenomenon to sense motion. This board features the PD-V10-G5, a miniature X-band microwave transceiver from Ningbo Pdlux Electronic Technology. The transmitter on this transceiver works on a 10.525GHz frequency over the patch antenna, with a 2-4kHz pulse repetition frequency. The strength of the sensor’s output, in other words, the detection range, depends on the Signal-to-Noise ratio.

Click library

  • Author : Nenad Filipovic
  • Date : May 2023.
  • Type : ADC/I2C type

Software Support

We provide a library for the Microwave 5 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.

Library Description

This library contains API for Microwave 5 Click driver.

Standard key functions :

  • microwave5_cfg_setup Config Object Initialization function.

    void microwave5_cfg_setup ( microwave5_cfg_t *cfg );
  • microwave5_init Initialization function.

    err_t microwave5_init ( microwave5_t *ctx, microwave5_cfg_t *cfg );

Example key functions :

  • microwave5_read_raw_adc Microwave 5 read raw ADC value function.

    err_t microwave5_read_raw_adc ( microwave5_t *ctx, uint16_t *raw_adc );
  • microwave5_read_voltage Microwave 5 read voltage level function.

    err_t microwave5_read_voltage ( microwave5_t *ctx, float *voltage );
  • microwave5_set_vref Microwave 5 set vref function.

    err_t microwave5_set_vref ( microwave5_t *ctx, float vref );

Example Description

This example demonstrates the use of the Microwave 5 Click board™ by reading and displaying the results of AD conversion and motion detection.

The demo application is composed of two sections :

Application Init

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. */
    microwave5_cfg_t microwave5_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.
    microwave5_cfg_setup( &microwave5_cfg );
    MICROWAVE5_MAP_MIKROBUS( microwave5_cfg, MIKROBUS_1 );
    err_t init_flag = microwave5_init( &microwave5, &microwave5_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 ( MICROWAVE5_OK == microwave5_read_voltage( &microwave5, &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 );
}

Application Task

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 ( MICROWAVE5_OK == microwave5_read_voltage( &microwave5, &voltage ) )
    {
        if ( ( ( voltage + MICROWAVE5_THRESHOLD ) < reference ) || 
             ( ( voltage - MICROWAVE5_THRESHOLD ) > reference ) )
        {
            if ( MICROWAVE5_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 = MICROWAVE5_FLAG_CLEAR;
                Delay_ms ( 100 );
            }
        }
        else
        {
            flag = MICROWAVE5_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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Microwave5

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.

PIR Click is a pyroelectric sensor which generates a voltage when exposed to infrared radiation emitted by live bodies. It is equipped with the PL-N823-01, an infrared sensor from KEMET that uses the pyrolectric effect of ceramic by absorbing infrared rays emitted from the human body, while the the white plastic Fresnel lens covering the sensor filters visible light.

IR Gesture 3 Click

0

IR Gesture 3 Click is a compact add-on board that provides contactless gesture recognition. This board features the ADPD1080, a photometric front-end from Analog Devices. The IR Gesture 3 Click allows gesture recognition in two dimensions, with a built-in optical filter and a sharp visible light cutoff. It eliminates the need for external lenses and preserves the dynamic range of the sensor when placed under sunlight or indoor lighting. It does not require a precise alignment because its sensor maintains a linear response within the ±35° angular field of view.
