VAV Press Click 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. The extremely low gas flow through the sensor ensures high immunity to dust contamination, humidity, and long tubing compared to other flow-based pressure sensors.
We provide a library for the VavPress 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.
This library contains API for VavPress Click driver.
vavpress_cfg_setup
Config Object Initialization function. vavpress_init
Initialization function. vavpress_default_cfg
Click Default Configuration function. vavpress_set_default_sensor_param
VAV Press set default sensor parameter function. vavpress_get_dif_press_and_temp
VAV Press get differential pressure and temperature function. vavpress_retrieve_electronic_signature
VAV Press retrieve electronic signature function. This library contains API for the Vav Press Click driver. This demo application shows an example of differential pressure and temperature measurement.
The demo application is composed of two sections :
Initialization of I2C module and log UART. After driver initialization and default settings, the app display retrieve the electronic signature and set the sensor parameters data.
This is an example that shows the use of a Vav Press Click boardâ„¢. Logs pressure difference value [ Pa ] and temperature [ degree Celsius ] value. Results are being sent to the Usart Terminal where you can track their changes.
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.

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.
