Temp&Hum 12 Click

TempHum 12 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 Library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

Example Description

This application measures temperature and humidity.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.TempHum12

Example Key Functions

  • temphum12_cfg_setup Config Object Initialization function.
void temphum12_cfg_setup ( temphum12_cfg_t *cfg );
  • temphum12_init Initialization function.
err_t temphum12_init ( temphum12_t *ctx, temphum12_cfg_t *cfg );
  • temphum12_default_cfg Click Default Configuration function.
void temphum12_default_cfg ( temphum12 *ctx );
  • temphum12_get_temperature Temperature data.
float temphum12_get_temperature ( temphum12_t *ctx, uint8_t temp_in );
  • temphum12_get_humidity Relative Huminidy data.
float temphum12_get_humidity ( temphum12_t *ctx );
  • temphum12_get_intrrupt_state Interrupt state.
uint8_t temphum12_get_intrrupt_state ( temphum12_t *ctx );

Application Init

Initializes driver init and configuration device for measurement.

void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum12_cfg_t cfg;
    uint16_t tmp;
    uint8_t read_reg [ 2 ];

    /** 
     * 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.

    temphum12_cfg_setup( &cfg );
    TEMPHUM12_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    temphum12_init( &temphum12, &cfg );

    temphum12_default_cfg( &temphum12 );
    
    Delay_ms ( 1000 );
    Delay_ms ( 500 );
    log_printf( &logger, "--- Start measurement ----\r\n" );
}

Application Task

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

void application_task ( void )
{
    float temperature;
    float humidity;

    temperature = temphum12_get_temperature( &temphum12, TEMPHUM12_TEMP_IN_CELSIUS);

    log_printf( &logger, "Temperature: %.2f \r\n", temperature );
    Delay_1sec( );
    
    humidity = temphum12_get_humidity( &temphum12 );

    log_printf( &logger, "Humidity: %.2f \r\n", humidity );
    
    log_printf( &logger, "-----------------------------\r\n" );
    Delay_1sec( );
}

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.
