Ozone 3 click

Ozone 3 Click is a compact add-on board suitable for ozone concentration detection and monitoring. This board features the 110-407, a high-performance ultra-thin electrochemical gas sensor from SPEC Sensors supported by the LMP91000, a high-precision integrated analog front-end IC (AFE) ideal for this sensing application. It provides the reference voltage required by the sensor and offers a choice between the analog output from the AFE IC buffered with the low noise Op-Amp and digital output from the 12-bit SAR A/D converter.

Click library

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

Software Support

We provide a library for the Ozone3 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 Ozone3 Click driver.

Example Description

This library contains API for the Ozone 3 click driver. This demo application shows an example of the O3 ppm data measurement.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After driver initialization the app set default settings.

void application_init ( void ) {
log_cfg_t log_cfg;
ozone3_cfg_t ozone3_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
ozone3_cfg_setup( &ozone3_cfg );
OZONE3_MAP_MIKROBUS( ozone3_cfg, MIKROBUS_1 );
err_t init_flag = ozone3_init( &ozone3, &ozone3_cfg );
if ( init_flag == I2C_MASTER_ERROR ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
ozone3_default_cfg ( &ozone3 );
log_info( &logger, " Application Task " );
Delay_ms( 300 );
}

Application Task

This is an example that shows the use of a Ozone 3 click boardâ„¢. Get and logs O3 ( Trioxygen ) data as ppm value. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) {
float o3_ppm = ozone3_get_o3_ppm( &ozone3 );
log_printf( &logger, "\tOzone : %.2f ppm \r\n", o3_ppm );
Delay_ms( 500 );
}

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.Ozone3

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.
