Barometer 5 Click is a compact add-on board used to measure air pressure in a specific environment. This board features the MS5637-02BA03, a high accuracy low voltage barometric and temperature sensor from TE Connectivity Measurement Specialties. The MS5637-02BA03 includes a high-linearity pressure sensor and an ultra-low-power 24-bit ΔΣ ADC with internal factory-calibrated coefficients, providing a precise digital 24-bit pressure and temperature value, and different operation modes allowing the user to optimize for conversion speed and current consumption. It comes with a configurable host interface that supports I2C serial communication and measures pressure in a range from 300mbar up to 1.2bar with an accuracy of ±2mbar over a wide operating temperature range.

Click library

  • Author : Nenad Filipovic
  • Date : Oct 2021.
  • Type : I2C type

Software Support

We provide a library for the Barometer5 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 Barometer 5 Click driver.

Standard key functions :

  • barometer5_cfg_setup Config Object Initialization function.

    void barometer5_cfg_setup ( barometer5_cfg_t *cfg );
  • barometer5_init Initialization function.

    err_t barometer5_init ( barometer5_t *ctx, barometer5_cfg_t *cfg );
  • barometer5_default_cfg Click Default Configuration function.

    err_t barometer5_default_cfg ( barometer5_t *ctx );

Example key functions :

  • barometer5_get_data Barometer 5 get data function.

    err_t barometer5_get_data ( barometer5_t *ctx, float *temperature, float *pressure );
  • barometer5_get_pressure Barometer 5 get pressure data function.

    err_t barometer5_get_pressure ( barometer5_t *ctx, float *pressure );
  • barometer5_get_temperature Barometer 5 get temperature data function.

    err_t barometer5_get_temperature ( barometer5_t *ctx, float *temperature );

Example Description

This library contains API for Barometer 5 Click driver. The demo application reads and calculate temperature and pressure data.

The demo application is composed of two sections :

Application Init

Initializes I2C driver and log UART. After driver initialization the app set default settings.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    barometer5_cfg_t barometer5_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.
    barometer5_cfg_setup( &barometer5_cfg );
    BAROMETER5_MAP_MIKROBUS( barometer5_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == barometer5_init( &barometer5, &barometer5_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( BAROMETER5_ERROR == barometer5_default_cfg ( &barometer5 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
    log_printf( &logger, "---------------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

This is an example that demonstrates the use of the Barometer 5 Click board™. In this example, display the Pressure ( mBar ) and Temperature ( degree Celsius ) data. Results are being sent to the Usart Terminal where you can track their changes.


void application_task ( void ) 
{
    static float temperature;
    static float pressure;

    if ( barometer5_get_data( &barometer5, &temperature, &pressure ) == BAROMETER5_OK )
    {
        log_printf( &logger, " Pressure    : %.2f mbar   \r\n", pressure );
        log_printf( &logger, " Temperature : %.2f C      \r\n", temperature );
        log_printf( &logger, "---------------------------\r\n" );
    }

    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.Barometer5

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.

Thermo 28 Click is a compact add-on board that accurately measures temperature. This board features the ams AG’s AS6221, a high-accuracy digital temperature sensor. The AS6221 consists of a Si bandgap temperature factory-calibrated sensor, 16-bit ADC, and a digital signal processor, offering a high accuracy of ±0.9°C. It provides temperature data to the host controller through a compatible I2C interface, reliability, user-selectable I2C addresses, and alert functionality, which triggers an interrupt to protect the device from excessive temperatures.
