Thermo 30 Click

Thermo 30 Click is a compact add-on board that accurately measures temperature. This board features the STS32-DIS-10KS, a third-generation, high-reliability, certified digital temperature sensor from Sensirion. It is a digitally calibrated and ISO17025-certified temperature sensor with an operating temperature range of -40 to 125°C.

Software Support

We provide a library for the Thermo 30 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Thermo 30 Click driver.

Standard key functions :

• thermo30_cfg_setup Config Object Initialization function.

  void thermo30_cfg_setup ( thermo30_cfg_t *cfg );

• thermo30_init Initialization function.

  err_t thermo30_init ( thermo30_t *ctx, thermo30_cfg_t *cfg );

• thermo30_default_cfg Click Default Configuration function.

  err_t thermo30_default_cfg ( thermo30_t *ctx );

Example key functions :

• thermo30_hw_reset Thermo 30 hw reset device function.

  void thermo30_hw_reset ( thermo30_t *ctx );

• thermo30_start_measurement Thermo 30 start measurement function.

  err_t thermo30_start_measurement ( thermo30_t *ctx, uint16_t cmd );

• thermo30_read_temperature Thermo 30 read temperature function.

  err_t thermo30_read_temperature ( thermo30_t *ctx, float *temperature );

Example Description

This example demonstrates the use of Thermo 30 Click board by reading and displaying the temperature measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and resets the device, and starts the periodic measurements at 1 mps with high repeatability.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    thermo30_cfg_t thermo30_cfg;  /**< Click config object. */

    /** 
     * 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.
    thermo30_cfg_setup( &thermo30_cfg );
    THERMO30_MAP_MIKROBUS( thermo30_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == thermo30_init( &thermo30, &thermo30_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( THERMO30_ERROR == thermo30_default_cfg( &thermo30 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Reads the temperature measurement in degrees Celsius and displays the results on the USB UART approximately once per second.

void application_task ( void ) 
{
    float temperature;

    if ( THERMO30_OK == thermo30_read_temperature( &thermo30, &temperature ) )
    {
        log_printf( &logger, " Temperature: %.2f deg C\r\n\n", temperature );
    }

    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Thermo30

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
