Temp&Hum 10 Click

TempHum 10 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.

• Click.TempHum10

Example Key Functions

• temphum10_cfg_setup Config Object Initialization function.

void temphum10_cfg_setup ( temphum10_cfg_t *cfg );

• temphum10_init Initialization function.

err_t temphum10_init ( temphum10_t *ctx, temphum10_cfg_t *cfg );

• temphum10_get_temperature Functions for read Temperature data.

float temphum10_get_temperature ( temphum10_t *ctx );

• temphum10_set_device_mode Functions for sets Device mode.

void temphum10_set_device_mode ( temphum10_t *ctx, uint8_t mode );

• temphum10_repeat_measurement Functions for repeat measurement.

void temphum10_repeat_measurement ( temphum10_t *ctx, uint8_t average );

Application Init

Initialization driver init and sets device mode

void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum10_cfg_t cfg;
    uint8_t tmp;

    temphum10_get_humidity( &temphum10 );
    log_info( &logger, "---- Application Task ----" );
}

Application Task

Reads Temperature and Humidity data and logs this data to USBUART every 1 sec.

void application_task ( )
{
    float temperature = 0;
    float humidity = 0;
    uint8_t tmp;
    
    tmp = TEMPHUM10_AM_TIMES_AVERAGE_MODE_8 | TEMPHUM10_AM_TEMP_AVERAGE_MODE_TIMES_16;
    temphum10_repeat_measurement( &temphum10, tmp );
    temperature = temphum10_get_temperature( &temphum10 );
    humidity = temphum10_get_humidity( &temphum10 );
    
    log_printf( &logger, " Temperature : %.2f \r\n", temperature );
    log_printf( &logger, " Humidity :  %.2f \r\n", humidity );
    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.
