Diff Press 3 click

Diff Press 3 Click is a compact add-on board that can measure differential pressure. It features the 2513130810401, a WSEN-PDUS differential pressure sensor from Würth Elektronik. The sensor is MEMS based and uses a piezo-resistive sensing principle. It is a fully calibrated pressure sensor with 15-bit digital and 11-bit analog outputs. In addition to pressure measurement, the 2513130810401 WSEN-PDUS sensor also has an embedded temperature sensor.

Software Support

We provide a library for the Diff Press 3 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.

Example Description

This library contains API for the Diff Press 3 Click driver. This demo application shows an example of differential pressure and temperature measurement.

The demo application is composed of two sections :

Application Init

Initialization of I2C and ADC module and log UART.

void application_init ( void )
{
log_cfg_t log_cfg;
diffpress3_cfg_t diffpress3_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
diffpress3_cfg_setup( &diffpress3_cfg );
DIFFPRESS3_MAP_MIKROBUS( diffpress3_cfg, MIKROBUS_1 );
err_t init_flag = diffpress3_init( &diffpress3, &diffpress3_cfg );
if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, "---------------------\r\n" );
Delay_ms( 100 );
}

Application Task

This example demonstrates the use of the Diff Press 3 Click board™. The demo application measures and display the Differential Pressure [kPa] and Temperature [degree Celsius] data. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
float pressure, temperature;
if ( DIFFPRESS3_OK == diffpress3_get_pressure( &diffpress3, &pressure ) )
{
log_printf( &logger, " Diff Pressure: %.3f [kPa]\r\n", pressure );
Delay_ms( 100 );
}
if ( DIFFPRESS3_OK == diffpress3_get_temperature( &diffpress3, &temperature ) )
{
log_printf( &logger, " Temperature: %.2f [C]\r\n", temperature );
Delay_ms( 100 );
}
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.DiffPress3

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.
