Barometer 5 click

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.

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;
barometer5_cfg_t barometer5_cfg;
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.
