Air quality 5 Click

Air quality 5 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.

Example Key Functions

• airquality5_cfg_setup Config Object Initialization function.

void airquality5_cfg_setup ( airquality5_cfg_t *cfg );

• airquality5_init Initialization function.

err_t airquality5_init ( airquality5_t *ctx, airquality5_cfg_t *cfg );

• airquality5_default_cfg Click Default Configuration function.

void airquality5_default_cfg ( airquality5_t *ctx );

• airq5_write_data Functions for write data in register.

void airq5_write_data ( airquality5_t *ctx, uint8_t reg, uint16_t data_b );

• airq5_read_data Functions for read data from register.

uint16_t airq5_read_data ( airquality5_t *ctx, uint8_t reg );

• airq5_set_configuration Functions for configuration.

void airq5_set_configuration ( airquality5_t *ctx, uint16_t config );

Application Init

Initializes device and configuration chip.

void application_init ( void )
{
    log_cfg_t log_cfg;
    airquality5_cfg_t cfg;
    airquality5.data_config = 0x8583;

    /** 
     * 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 ----" );

    airquality5_cfg_setup( &cfg );
    AIRQUALITY5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    airquality5_init( &airquality5, &cfg );
}

Application Task

Reads the values of CO, NH3 and NO2 sensor and logs data on USBUART every 500ms.

void application_task ( void )
{
    uint16_t NO2_sensor_data;
    uint16_t NH3_sensor_data;
    uint16_t CO_sensor_data;
 
    CO_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_CO );
      
    NO2_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_NO2 );
    log_printf( &logger, " NO2 data: %d\r\n", NO2_sensor_data );
      
    NH3_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_NH3 );
    log_printf( &logger, " NH3 data: %d\r\n", NH3_sensor_data );
     
    CO_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_CO );
    log_printf( &logger," CO data: %d\r\n", CO_sensor_data );
     
    log_printf( &logger, " -------- ");
    Delay_ms ( 200 );
}

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.
