VAV Press Click Board
VAV Press Click Board
The VAV Press Click Board™ is a compact add-on board that contains a board-mount pressure sensor. This board features the LMIS025B, a low differential pressure sensor from First Sensor (part of TE Connectivity). It is based on thermal flow measurement of gas through a micro-flow channel integrated within the sensor chip. The innovative LMI technology features superior sensitivity, especially for ultra-low pressures ranging from 0 to 25Pa. Compared to other flow-based pressure sensors, the extremely-low gas flow through the sensor ensures high immunity to dust contamination, humidity, and long tubing.
The VAV Press Click Board™ is suitable for pressure measurements in Variable Air Volume (VAV) building ventilation systems, industrial and medical respiratory applications.
Software Support
We provide a library for the VAV Press Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on mikroE Github account.
Library Description
This library contains API for the VAV Press Click Board™ driver.
Key Functions
vavpress_cfg_setup
- Config Object Initialization function.vavpress_init
- Initialization function.vavpress_default_cfg
- Click Default Configuration function.
Example Description
This library contains API for the VAV Press Click Board™ driver. This demo application shows an example of differential pressure and temperature measurement.
void application_task ( void ) { err_t error_flag = vavpress_get_dif_press_and_temp( &vavpress, ¶m_data, &diff_press, &temperature ); if ( error_flag == VAVPRESS_OK ) { log_printf( &logger, " Diff. Pressure : %.4f Parn", diff_press ); log_printf( &logger, " Temperature : %.4f Crn", temperature ); log_printf( &logger, "--------------------------------rn" ); Delay_ms( 2000 ); } else { log_error( &logger, " Communcation Error. " ); log_info( &logger, " Please, run program again... " ); for ( ; ; ); } }
The full application code, and ready to use projects can be installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on mikroE Github account.
Other mikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.VavPress
Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The VAV Press Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
