Hydro Probe Click

Hydro Probe 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.

• Author : MikroE Team
• Date : Jul 2020.
• Type : I2C type

Software Support

Example Description

This demo application measures moisture.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.HydroProbe

Example Key Functions

• hydroprobe_cfg_setup Config Object Initialization function.

void hydroprobe_cfg_setup ( hydroprobe_cfg_t *cfg );

• hydroprobe_init Initialization function.

err_t hydroprobe_init ( hydroprobe_t *ctx, hydroprobe_cfg_t *cfg );

• hydroprobe_avg_val Get average value function.

uint16_t hydroprobe_avg_val ( hydroprobe_t *ctx );

• hydroprobe_min_val Get minimum value function.

uint16_t hydroprobe_min_val ( hydroprobe_t *ctx );

• hydroprobe_rel_env_hum Get Relative humidity of the environment function.

uint8_t hydroprobe_rel_env_hum ( hydroprobe_t *ctx, uint16_t dry_val, uint16_t wet_val );

Application Init

Initalizes I2C driver, prerforms calibration and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    hydroprobe_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.

    hydroprobe_cfg_setup( &cfg );
    HYDROPROBE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    hydroprobe_init( &hydroprobe, &cfg );
    
    Delay_ms ( 100 );

    log_printf( &logger, "---------------------\r\n" );
    log_printf( &logger, "  Hydro Probe Click  \r\n" );
    log_printf( &logger, "---------------------\r\n" );
    hydroprobe_calib( );
    log_printf( &logger, "     Calibrated      \r\n" );
    log_printf( &logger, "---------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Task

This example shows the capabilities of the Hydro Probe Click by measuring environment moisture content and displaying it in percent via USB UART.

void application_task ( void )
{
    humy_val = hydroprobe_rel_env_hum( &hydroprobe, dry_val, wet_val );
    log_printf( &logger, "Environment moisture content: %d %% \r\n ", ( uint16_t ) humy_val );
    log_printf( &logger, "------------------------------\r\n" );
    Delay_ms ( 1000 );
}

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.
