Water Detect Click

Water Detect Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

• Date : Dec 2019.
• Type : GPIO type

Software Support

Example Description

Water Detect Click is used for detecting water and other electroconductive liquids. If the detection area is wet the output of Microchip's MCP606 CMOS op-amp will go positive, signaling the presence of liquid.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.WaterDetect

Example Key Functions

• waterdetect_cfg_setup Config Object Initialization function.

void waterdetect_cfg_setup ( waterdetect_cfg_t *cfg );

• waterdetect_init Initialization function.

err_t waterdetect_init ( waterdetect_t *ctx, waterdetect_cfg_t *cfg );

• waterdetect_default_cfg Click Default Configuration function.

void waterdetect_default_cfg ( waterdetect_t *ctx );

Example key function :

• waterdetect_get_status Get the status of the water detection function.

uint8_t waterdetect_get_status ( waterdetect_t *ctx );

Application Init

Initializes GPIO and LOG structures, set INT pins as input and starts to write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    waterdetect_cfg_t cfg;

    /** 
     * 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.

    waterdetect_cfg_setup( &cfg );
    WATERDETECT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    waterdetect_init( &waterdetect, &cfg );
    Delay_100ms();
    
    log_printf( &logger, "  Initialization Driver   \r\n" );
    log_printf( &logger, "------------------------- \r\n" );
    log_printf( &logger, "  Wait to detect water...  \r\n" );
    log_printf( &logger, "------------------------- \r\n" );
}

Application Task

Reads device status and determines if there are water presence or not.

void application_task ( void )
{
    wd_state = waterdetect_get_status( &waterdetect );

    if ( wd_state > wd_state_old )
    {
        log_printf( &logger, " >  Water is detected  < \r\n" );
        log_printf( &logger, "------------------------- \r\n" );
        wd_state_old = 1;
    }

    if ( wd_state < wd_state_old )
    {
        log_printf( &logger, " There is no water \r\n" );
        log_printf( &logger, "------------------- \r\n" );
        wd_state_old = 0;
    }
}

Note

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
